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).
