Description

Magnetic properties of the normal cubic spinel CdFe2O4 have been investigated on a single crystal above the spin-ordering temperature similar to 10 K, in uniform applied magnetic fields 030 K, with the Curie constant in quantitative agreement with the theoretical value for Fe3+ ions in the 6S/sub 5/2/ state. We argue that the fraction x of Fe(A) ions, if any, is very small (x<10/sup -2/) so that the nonlinearity cannot be attributed to the site-dilution characteristics of random-field systems. Instead, it is attributable to the large frustration inherent in the topology of the normal spinel cubic lattice
