DEPENDENCE OF SUPEREXCHANGE INTERACTION ON FE(3+)-O(2-) - FE(3+) LINKAGE ANGLE,

Abstract

The Neel temperature of the orthoferrites is calculated assuming a constant distance between Oxygen and Iron ions and that the superexchange integral varies as the cosine of the linkage angle. The calculated values fit well the measured Neel temperatures which cover a range of about 120K. (Author)
