Homogeneity and Magnetic Susceptibility in Some Substituted Cadmium Spinels,

Abstract

The normal spinels CdFe204, CdGa1.8Fe0.204 and CdRh1.8Fe0.204 were prepared, and their magnetic susceptibilities were measured. The low micro eff value of 4.72 (5) micro B found for CdFe204 can be attributed to hybridization of the 6S and 4G wavefunctions resulting from spin-orbit interaction coupled with strong crystal fields having trigonal components at the spinal B-sites. Magnetic crystal fields having trigonal components at the spinel B-sites. Magnetic susceptibility was sensitive to the homogeneity of samples of CdGa1.8Fe0.204 and CdRh1.8Fe0.204, which was dependent upon the method of preparation. For homogeneous samples, the magnetic susceptibility approaches the theoretical value for high-spin Fe3+(3d5). The slight remaining discrepency from spin-only moment is due to the statistical existence of a few small Fe3+ clusters.
