M?SSBAUER STUDY OF MAGNETIC STPUCTURE IN LITHIUM-ZINC FERRITES

The M?ssbauer spectra of the ferrite system, Li(0.5(1-x))ZnxFe(2.5-0.5x)O4, were studied at 77 K, 195 K and room temperature in an external magnetic field parallel to the gamma-ray direction. With increasing x and decreasing temperature, the second and the fifth lines of the six magnetic splittings were observed to become clearer, which proves convincingly the existence of canting of the moment of Fe3+ populated in the (B)-sublattice of the LiZn-ferrites. The agreement between magnetizations calculated on the basis of M?ssbauer parameters and measured by the magnetic experiment is satis-factory.
