Abstract

Since M~ssbauer spectrum parameters are quite sensitive to the nearest surroundings variation, the M~ssbauer spectroscopy enables one to obtain information concerning the cation and anion mutual distribution on the atomic level. The magnetic properties of dielectric crystals in relation to the types of the constituting cations and their distribution in nonequivalent sites is studied rather elaborately. But the problem of the anionic influence has been raised rather recently /1-3/. The magnetic ordering is explained by the magnetic ions exchange interaction through diamagnetic ligands. Thus the direct anionic influence on the exchange interactions and on magnetic microstructure formation should be expected. In order to investigate the anionic influence a M6ssbauer study of ferrites with various anionic substitution was carried out
