Description

Crystallochemical and magnetochemical studies of cerium atom state in solid solutions of Y0.9Ce0.1CaCrxAl1-xO4(1) and Y0.8Ce0.1Ca1.1CrxAl1-xO4(2), where 0 ≤ x ≤ 0.1, are conducted. Atomic coordinates and interatomic distances are calculated. It is shown that the reduced state of cerium(3) atoms is realized in solid solutions (1), and cerium(4) state - in solid solutions (2)

Abstract (Russian)

Проведено кристаллохимическое и магнетохимическое исследование состояния атомов церия в твердых растворах Y0.9Ce0.1CaCrxAl1-xO4(1) и Y0.8Ce0.1Ca1.1CrxAl1-xO4(2), где 0 ≤ x ≤ 0.1. Рассчитаны координаты атомов и межатомные расстояния. Восстановленное состояние атомов Ce(3) реализуется в твердых расстворах (1), состояние Ce(4) - в растворах (2)
