Abstract

Lead magnesium niobate ceramics have been studied by high resolution electron microscopy (HREM). The electron diffraction patterns and high resolution images show the existence of a superstructure along the [111] direction of the perovskite cubic unit cell. The origin of this superstructure is discussed.

    High-dielectric-constant materials have been paid much attention due to their extensive applications in microelectronics fields such as capacitance and memory devices. Ferroelectric perovskite ceramics, e.g., BaTiO3 (BTO) and Pb (ZrxTi1−x)O3 (PZT) [1–4], show extraordinary high dielectric constants as well as low dielectric losses around the Curie temperature TC. Non-ferroelectric materials, such as perovskite-related CaCu3Ti4O12 (CCTO) [5] and non-perovskite Li0.05Ti0.02Ni0.93O (LTNO) [6], have comparatively high dielectric constants (εr∼104–105) at room temperature which is generally ascribed to the blocking layers between the particles [7,8].

    In this compound, the element of disorder is introduced by the occupation of the B-site by two ions with different valences (Mg2 + and Nb5 +) and sizes (0.72 Å for Mg2 + and 0.64 Å for Nb5 +). Interestingly, the initial explanation of relaxor behavior in PMN went in the opposite direction by invoking the presence of chemically ordered domains which result in charge imbalance (Husson et al., 1988). However, this scenario has many problems.
