Researchers from Heidelbergs Kirchoff Institute of Physics investigated the magnetization process down to the mK-regime and the magnetic phase diagrams of the hexagonal perovskite rare earth oxide GdInO3. To compensate the heavy volatilization of In2O3 the single crystals were grown under an oxygen pressure of 30 bar using the ScIDre optical floating zone furnace HKZ.
The authors state that the system evolves long-range antiferromagnetic order at TN = 2.1 K and exhibits considerable magnetic frustration (|Θ|/TN ≃ 5). GdInO3 features a broad 1/3 plateau indicating an up-up-down spin configuration for B||c but is absent for B||ab (suggesting easy-axis anisotropy).
