Electrical Conductivities of Liquid In₂Te₃ and InTe₄ Alloys Containing Transition Metal Solutes

抄録

The electrical conductivity of the liquid InTe₄ alloy increases with addition of Fe, Co and Ni solutes, and decreases with addition of Ti, V, Cr and Mn solutes. For the liquid In₂Te₃ solvent, the trend of the increase in the conductivity in the series of transition metal solutes exhibits a large peak at Ni and a small peak at V. The increase in the conductivity for Fe, Co and Ni solutes is considerably larger than that for other transition metal solutes. The remarkable increase in the conductivity caused by addition of transition metal solutes is closely related to the increase in the total density of states at the Fermi level due to the sp-d admixture effect.
