Magnetic Susceptibilities of Transition Metal Solutes in Liquid In₂Te₃ and InTe₄ Alloys

抄録

The enhancement of the susceptibilities χ_d of liquid In₂Te₃, InTe₄ and Te caused by addition of Cr, Mn and Fe solutes decreases gradually with increasing temperature. This suggests that Cr, Mn and Fe ions are in a magnetic state in these liquid solvents. Similarly, the d states of V, Co and Ni solutes become magnetic in liquid InTe₄ and In₂Te₃ alloys. The trend of χ_d versus transition metal solute exhibits a large peak at Mn. The low density of states of a solvent at the Fermi level is reflected on large values of χ_d in these liquid solvents, compared with the values of χ_d in liquid metals. It is found that χ_d(Fe)>χ_d(Cr) and χ_d(Co)>χ_d(V) in these liquid solvents. This relationship is attributed to a low density of conduction electrons of a solvent.
