Heat Capacity Measurements

Heat capacity measurements have been performed on solid CH3D over the range 0.15 < T < 4 K where a large Schottky anomaly occurs. The entropy change in the anomaly is estimated to be 1.80 ± 0.10R which is about 14% less than that corresponding to complete orientational ordering of the molecules and total conversion of nuclear spin symmetry species. Some time effects associated with thermal equilibration have also been studied.

AbstractSome compositions of Ni-Mn-X (X = Ga, In, Sn) ferromagnetic shape memory alloys exhibit a first order magnetostructural phase transition. Magnetic entropy change ΔSm in the vicinity of this transition has been studied by magnetization and heat capacity measurements. Comparison of these results point to a large difference in magnitudes of ΔSm obtained from magnetization and heat capacity data. It is suggested that this discrepancy originates from overestimation of \Delta S_m determined from the magnetization measurements and underestimation of ΔSm obtained from the heat capacity measurements.
