Low temperature properties of some (R)indium compounds

The magnetic susceptibilities of RIn3 compounds, where R represents the rare earth elements Y, Ce, Pr, Nd, and Dy have been measured. The susceptibilities found are consistent with literature values.; The low temperature heat capacity of ErIn3 has been studied because of its potential for use as a low temperature regenerator material. Slight variations from stoichiometry have shown to affect the heat capacity of ErIn3. Also, substituting some or all of the erbium with other rare earth elements causes the temperature at which the magnetic transformation occurs to shift. The (HoxEr1-x)In3 system has been extensively studied. Some of these samples show anomalous behavior in both their lattice parameters and heat capacity values. In addition, several other (RxEr1-x)In3 samples have been measured for x = 0.05 and 0.1, and R = Y, Ce, Pr, and Dy. Finally, the heat capacity of ErIn3 is found to be affected by physical deformation of the material.
