Studies of the ferromagnetic Kondo lattice system of single crystal CeZnSb$_{2}$

ORAL

Abstract

We have grown single crystals of the ferromagnetic Kondo lattice system CeZnSb$_{2}$. The ferromagnetic ground state was confirmed by neutron scattering. In addition, a small hysterisis in magnetization data indicates soft ferromagnetism. The large heat capacity coefficient (350 mJ/mol-Ce K$^{2})$ below the transition temperature, on the other hand, suggests a heavy mass state even below the magnetically ordered state. Thermodynamic, magnetic, and transport properties along with pressure experiments will be presented. The origin of such unusual magnetism will be discussed. This work was supported by NSF DMR-0433560.
