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

reportActive / Technical Report | Accession Number: AD0615645 | Need Help?

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
