Ku. Neumann et Kra. Ziebeck, ARROTT PLOTS FOR RARE-EARTH ALLOYS WITH CRYSTAL-FIELD SPLITTING, Journal of magnetism and magnetic materials, 144, 1995, pp. 967-968
The effects of the crystal field (CF) splitting of rare earth atoms in
intermetallic compounds on Arrott plots are investigated. It is shown
that the combination of a local influence as determined by the CF spl
itting and the magnetic interactions between the moments on different
sites leads to curvature of the Arrott plots.
