The spin state of manganese atoms in Sr2MnSbO6 complex oxides

The magnetic susceptibility of Sr₂MnSbO₆ solid solutions in a Sr₂AlSbO₆ diamagnetic diluent is investigated. Variation in the magnetic characteristics with temperature and the solution concentration indicates the coexistence of two spin states of manganese atoms: low-spin and high-spin. The possibility of spin transitions is due to temperature-dependent local distortions in the crystal structure of the solutions.
