We have synthesized α-LiFe1−xInxO2 (x=0, 0.001, 0.01, 0.05, and 0.1) powders by calcination of Li2CO3, Fe2O3 and In2O3 mixtures. In X-ray diffraction, the sample with larger x value showed larger lattice constant of the cubic NaCl-type structure. Aside from electron diffraction patterns of the cubic unit cell with diffuse scattering for both the samples, the x=0 sample demonstrated a doubled structure of the cubic unit cell with wavy diffuse scattering, though the x=0.1 sample exhibited the doubled structure with less intensive diffuse scattering. In cooling history-dependent dc susceptibilities, the bifurcation point of the x=0 sample was ≈90 K, and it lowered from 87 to 44 K with increasing the x value from 0.001 to 0.1. Dilution of α-LiFeO2 with nonmagnetic In3+ ions suppressed chemical cluster formation at room temperature and reduced temperature of ferromagnetic cluster formation.
