Abstract

Non-linear behaviour in the ln(t) law of time depenence of magnetisation is found to be governed by the distribution function of the energy barriers f(ΔE) within the system. The variation of the magnetisation with ln(t) is predicted to be concave downwards when f(ΔE(t)) is increasing with time, and concave upwards when f(ΔE(t)) is decreasing with time. A linear ln(t) law is only the case when f(ΔE(t)) is approximately constant with time.

A new paradigm for exchange bias in polycrystalline thin films
2010, Journal of Magnetism and Magnetic Materials
In this paper we provide a review and overview of a series of works generated in our laboratory over the last 5 years. These works have described the development and evolution of a new paradigm for exchange bias in polycrystalline thin films with grain sizes in the range 5–15 nm. We have shown that the individual grains in the antiferromagnetic (AF) layer of exchange bias systems contain a single AF domain and reverse over an energy barrier which is grain volume dependent. We show that the AF grains are not coupled to each other and behave independently. Understanding this process and using designed measurement protocols has enabled us to determine unambiguously the blocking temperature distribution of the AF grains, the anisotropy constant (K_AF) of the AF, understand the AF grain-setting process, and predict its magnetic viscosity. We can explain and predict the grain size and film thickness dependence of the exchange field H_ex. We have also studied interfacial effects and shown that there are processes at the interface, which can occur independently of the bulk of the AF grains. We have seen these effects via studies of trilayers and also via the field dependence of the setting process which does not affect the blocking. From separate experiments we have shown that the disordered interfacial spins exist as spin clusters analogous to a spin glass. These clusters can order spontaneously at low temperatures or can be ordered by the setting field. We believe it is the degree of order of the interfacial spins that gives rise to the coercivity in exchange bias systems. Based on this new understanding of the behaviour of the bulk of the grains in the antiferromagnet and the interfacial spins we believe that we have now a new paradigm for the phenomenon of exchange bias in sputtered polycrystalline thin films. We emphasize that the phenomenological model does not apply to core–shell particles, epitaxial single-crystal films and large grain polycrystalline films.
Analytical way to model magnetic transients and accommodation
2007, Physica B: Condensed Matter
The paper demonstrates the use of the model, based on hyperbolic geometry, by applying it on magnetic transient and reptation problems. By using the rules of the natural geometry inside of the major hysteresis loop, the model provides an easy analytical solution to the complex phenomena of reptation, accommodation and the general transient behaviour of hysteretic materials.
It compares favourably with published examples selected from the literature and results of other models. The mathematics used is far simpler than that of other models with no need for heavy computer time and time consuming numerical approximation. On reptation the model follows the pattern set by published experimental data.
The mathematics described here offers an analytical solution to the problem of accommodation instead of numerical approximation. It provides an ideal tool in experiments and theoretical work alike.
Effect of Magnetic Interaction on Thermally Activated Reversal in a Magnet With a Distribution of Energy Barriers
2006, Journal of Iron and Steel Research International
The time dependence of magnetization is usually expressed as M(t)=M₀-SInt [see Proc. Phys. Soc. 62, 562 (1949)] for magnetic viscosity experiments. Considering magnetic interaction during the thermal activation process, a form as M(t)=M₀-SIn(t+t₀) is deduced. The dipolar interaction and exchange coupling in a magnet can lead to positive and nonpositive t₀, respectively. In the experiments of the magnetic viscosity for nanocrystalline Pr₂Fe₁₄B ribbons, the existence of positive t₀ is confirmed.
An investigation of time-dependent domain wall pinning effects in Tb/Fe multilayer thin films
2002, Journal of Magnetism and Magnetic Materials
Reverse domain nucleation time measurements have been performed on two Tb/Fe multilayer magneto-optic films exhibiting different degrees of domain wall pinning. A linear relationship between ln (reverse domain nucleation time) and the applied field has been predicted and observed for a sample exhibiting weak domain wall pinning. This is in agreement with theoretical work presented which addresses time dependence in systems possessing weak domain wall pinning. A non-linear relationship applicable over a restricted field range has been derived for a sample exhibiting strong domain wall pinning. Experimental results have indicated that this relationship is also valid.
Fluctuation fields and reversal mechanisms in granular magnetic systems
2002, Journal of Magnetism and Magnetic Materials
In this paper, the behaviour of the fluctuation of the fluctuation field (H_f) and its relationship with the activation energy for reversal in magnetic systems is examined. At a constant level of magnetisation, the link between thermal energy and field induced changes in the magnetisation of the system using different forms of the equation of state are found to give the same value of H_f. Accordingly, the former S/χ_irr and the $∂ H/ ∂ln (M ̇_{irr})|_{M_{irr}}$ techniques for determining H_f are found to be consistent so long as the analysis of H_f is made at the same constant level of irreversible magnetisation (M_irr). Both techniques show that the fluctuation field can be determined using H_f=ΔH/Δln(t)|_{M_irr} which is more accessible to experiment. Hence, one can define H_f as the change in field required to maintain the magnetisation of the system unchanged during a time interval of Δln(t)=1.
The behaviour of the fluctuation field in systems that contain a distribution of activation energies (f(ΔE)) is found to be governed by the nature of f(ΔE). For the case where this distribution arises from distributions of both particle volumes and anisotropy fields, the variation of H_f with M_irr is predicted to be approximately constant when both distributions have comparable standard deviations. Also H_f is predicted to be constant with M_irr is the case where both distributions become extremely narrow (i.e. the case of a single activation energy). Hence H_f remaining constant with M_irr cannot be used to show that the activation energy in the system is constant. In addition if the system contains a single activation energy, a constant value of H_f cannot be used to distinguish between reversal mechanisms such as coherent rotation or weak domain wall pinning.
Determination of fluctuation field and activation volume in metal evaporated tape through magnetic relaxation
2000, Journal of Magnetism and Magnetic Materials
Capacity increase is one of the main driving forces in innovating magnetic recording products. Therefore, it is important to know the physical limit of the storage density for a given recording medium. One way to determine this value is by analyzing magnetic relaxation. From the time dependence of the magnetization we derive the activation volume, i.e. the volume that nucleates magnetic reversal for fields of the order of the coercivity, and helps to set an upper limit on the storage density. We discuss experiments on metal evaporated (ME) tape, using a special vibrating sample magnetometer, capable of supplying a constant internal vector field. We find a nonlinear relation between magnetization and the natural logarithm of time, indicating a narrow distribution of the activation energies. Due to experimental limitations the method is only capable of giving an order of magnitude estimate. We find an activation volume of approximately 1×10⁴ nm³ for a Sony HI8 tape (first generation commerical Sony HI8 tape from 1992), leading to an estimated maximum data density of 10 Gbit/in².
