Re-arrangement of cationic distribution in partially inverse spinel NiAlO by using chemical pressure perturbation is studied. Structural, impedance and magnetic analysis suggest presence of regions/domains inside the grain/bulk with same lattice arrangement but varying in cationic oxidation state. Perturbing the cationic distribution in the grain via low concentrations of ambivalence substituent rearranges the cationic distribution across these domains within the partially inverse spinel lattice without disturbing the crystal structure. A comprehensive explanation on the origin & tunability of cationic distribution within the partially-inverse lattice is proposed.
研究了通过化学压力扰动对部分反尖晶石NiAlO中阳离子分布进行重新排列的情况。结构、阻抗和磁性分析表明，在晶粒/块体内部存在具有相同晶格排列但阳离子氧化态不同的区域/畴。通过低浓度的矛盾取代基扰动晶粒中的阳离子分布，可在不干扰晶体结构的情况下，重新排列部分反尖晶石晶格中这些畴之间的阳离子分布。本文提出了关于部分反晶格中阳离子分布的起源和可调性的全面解释。
