Abstract

The giant magnetoresistance (MR) effect has been investigated for NiFeCoCu multilayers (MLs) with various NiFeCo alloy composition. The composition was varied along the zero magnetostriction constants line in the Co-rich (>35at%) areas. The MLs containing less than 15 at% Fe exhibited a MR ratio above 20% at a Cu thickness of about 2 nm.

    Citation Excerpt :

    Compared to Co90Fe10/Cu multilayers with the GMR ratio of 25–33% [18,19], the maximum magnetoresistance of many CoFeNi/Cu multilayers is only 10–15%. Magnetoresistance above 20% was obtained using Co-rich alloys in which the Fe content does not exceed 15 at% [14]. In our recent studies [20] it was shown that magnetoresistance in multilayers based on the Co70Fe20Ni10 alloy reaches 31% and coincides with that of Co90Fe10/Сu multilayers of a similar composition.

  • Giant magnetoresistance (GMR) behavior of electrodeposited NiFe/Cu multilayers: Dependence of non-magnetic and magnetic layer thicknesses

    2017, Journal of Magnetism and Magnetic Materials
    Citation Excerpt :

    Furthermore, the GMR behavior of electrodeposited multilayers can be improved by several physical deposition parameters such as ferromagnetic and nonmagnetic layer thickness, bilayer number and substrate type [11]. For the magnetoresistive applications, a high sensitivity is required and therefore the materials with large GMR change at the small magnetic fields are needed [12]. This can be accomplished by decreasing coercive field of the ferromagnetic layers [13].
