Magnetization, Velocity of Sound, and Specific Heat ofSc3In

Abstract

The magnetization at 1.5 and 4.2°K and the velocity of sound in zero field of ${\mathrm{Sc}}_3$In from 1.5 to 300°K and in applied fields at 1.5 and 4.2°K are reported. The magnetic behavior exhibits essentially no coercive field, remanence, or hysteresis. A thermodynamic formula is obtained relating the field dependence of the velocity of sound with magnetostriction and magnetic susceptibility. A qualitatively successful comparison is made using our results and the magnetostriction data of Fawcett and Meincke. Specific-heat data at zero field and 1.3 kOe are reported and are related thermodynamically to the magnetization data.
