Abstract:

Curie temperatures of 14 different orthoferrites with the chemical formula RFeO3, RY La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu were measured by differential thermal analysis. Hyperfine interactions of the Fe57 nucleus in the same materials were determined from their Mossbauer spectra. It is found that the quadrupole splitting, with the exception of the case of Sm, isomer shift, Curie temperature and internal field vary regularly with the ionic size of R. Author
