Magnetism of intermetallics

Original properties were recently discovered in itinerant electron systems , for example , reentrant ferromagnetsm in RMn2GE2, and weak ferromagnetism in PdTiAl, when the composition elements are individually non-magnetic. In rare earth-transi- tion metal compounds (RM), the strength of the R3M29 compounds. In rare-earth compounds, metamagnetic transitions were associated with long-range competing interactions.Magnetism and superconductivity coexist in the newly discovered RM borocarbides.
