Fine structure and magnetism of the cubic oxide compound Ni 0.3 Zn 0.7 O

摘要: The fine structure and spin system of the cubic oxide Ni0.3Zn0.7O compound prepared from initial hexagonal phase by quenching a sample with high temperature applying an external hydrostatic pressure to it have been studied using magnetic measurements, synchrotron X-ray diffraction. It has revealed that diffraction patterns this contain weak diffuse maxima wave vectors q = (1/6 1/6 1/6)2π/a (1/3 1/3 1/3)2π/a, along strong Bragg peaks phase. shown origin is due longitudinal transverse displacements ions respect symmetric crystallographic directions {111} type. reasons for ion displacement specific features strongly correlated briefly discussed.
