Abstract

Characterization of a ferromagnetic In_1.9Mn_0.1O_3−δ oxide prepared by a conventional solid-state synthesis route is reported. Lattice parameter a (

) obtained from Rietveld refinement shows distinct shrinkage of the lattice constant indicating an actual incorporation of Mn ions into the In₂O₃ lattice. The T_c for Mn-doped In₂O₃ oxide is 46 K. The effective magnetic moment (μ_eff) is 2.87 μ_B corresponding to that of either tetrahedrally or octahedrally coordinated Mn³⁺ in an intermediate spin state (μ_eff=2.83 μ_B). SEM EDS mapping showed homogeneous distribution of all ions in the sample, and the chemical composition calculated from EDS spot analysis matches nominal values.
