Ferrimagnetic phase transition

Since the sign of the first term is invariant with the sign of the interaction and p > 0, is parallel to MB if ct > cc and Ma is antiparallel to Mb if ct < cc. There occurs a first-order anti ferromagnetic ferrimagnetic phase transition at a temperature Te such that... 

Values obtained by powder neutron diffraction for the ferrimagnetic phase [the number of magnetic atoms (g — lgB) and non-magnetic atom is the same, see fig. 3.6. and text]. h The lower transition from antiferromagnetism to ferro/ferrimagnetism. 

Much of the recent work (e.g. Harris and Zobin, 1977 Chen and Lubensky, 1977 Patterson et al., 1978 Harris et al., 1978) on the magnetic phase transition in amorphous alloys has centered on the conditions under which a low-T spin-glass state is formed of the Edwards-Anderson (1975) type in place of a true ferromagnetic (or ferrimagnetic) state below T. ...
