Physical Properties of XTSb[(X= Eu, Sr), (T= Ag, Au)] single crystals

ORAL

Abstract

Single crystals of XTSb [(X= Eu, Sr), (T= Ag, Au)] were grown by the solution growth by using self flux [1]. These single crystals were investigated by powder X-ray diffraction at room temperature and the structure was successfully refined to be the hexagonal (space group P63/mmc) crystal structure . Temperature dependent magnetic susceptibility measurements indicate antiferromagnetic ordering for magnetic compounds (e.g. TN = 6 K for EuAgSb). Density functional theory calculations find that the band inversion giving a Dirac point is present in the non-magnetic Au compounds, but not the Ag compounds. Thermodynamic and transport data on the non-magnetic SrAgSb, SrAuSb and magnetic EuAgSb, EuAuSb will be presented and compared.
