Abstract

Abstract The magnetic susceptibilities of liquid CrTe, MnTe and FeTe alloys decrease with increasing temperature. The effective Bohr magneton numbers P obtained from the Curie-Weiss law are about 4.31, 5.53 and 4.42 for liquid CrTe, MnTe and FeTe, respectively. The large values of P suggest that the d-states of Cr, Mn and Fe ions in these liquid alloys are split into two sub bands of spin up and spin down due to the intra-atomic Coulomb interaction. The susceptibilities of liquid TiTe, VTe, CoTe and NiTe alloys show non-magnetic behaviour. However, those of liquid VTe and CoTe alloys become magnetic on increasing the concentration of the transition metal. The density of d-states at the Fermi level can be estimated from the susceptibilities of transition metal alloys for a non-magnetic state. These results are consistent with the trend of the electrical conductivities of liquid transition metal-Te alloys.
