Anisotropic Magnetization And Transport Properties Of Ragsb₂ (R=Y, La-Nd, Sm, Gd-Tm) , Kenneth Duane Myers

Retrospective Theses and Dissertations

Anisotropic measurements of the magnetic and transport properties have been performed on high quality single crystals of the RAgSb2 series of compounds with R = Y, La-Nd, Sm, Gd-Tm. For all of these compounds except for ErAgSb2 and TmAgSb2, strong magnetic anisotropy created by CEF splitting of the Hund's rule ground state confines the moments to the basal plane. Additional anisotropy within the basal plane is also observed in DyAgSb2, leading to a series of metamagnetic transitions. Detailed analysis of the saturated moment and critical fields allows a determination of the net distribution of magnetic moments within each phase. The ...
