New rare earth intermetallic compounds: synthesis, characterisation, electric and magnetic properties

Description

Recent physical results related to some binary and ternary rare earth intermetallic compounds are presented. The investigation has been addressed to different objectives: the study of the magnetothermodynamic properties of some binary and ternary Gd compounds is devoted to a possible technological use in the magnetic refrigeration and as a components of heat pumps; the study of the magnetism in new ternary rare earth intermetallic compounds contributes to the understanding of the mechanisms responsible of the 4f-4f and 4f-3d interactions. Finally, in the RMn6B6 compounds with B = Ge, Sn the analysis of the influence of the partial substitution of the non magnetic element B with Ga or In gives informations about the influence of the chemical substitution on the crystallographic structure, the Valence electron Concentration, the different magnetic interactions and the magnetic transport properties of these phases.
