Abstract

The low temperature heat capacity, magnetic susceptibility and electrical resistivity were studied for a series of Ce intermetallic compounds. No heavy fermion behavior was found in these compounds. CePtGa[subscript]3 has a rounded peak at ~1.7K in its heat capacity, which is shifted to higher temperatures in magnetic fields (~6K at 9.8T). The origin of this peak is believed to be due to a spin glass type transition. CeCd[subscript]11 has an unusual temperature dependence of its heat capacity which is due to a crystalline electric field (CEF) effect which occurs at an exceptionally low temperature. The CEF effect also plays an important role in CeGa[subscript]2. Antiferromagnetic phase transitions were found in CeHg[subscript]3, CeCd[subscript]2, CeCd[subscript]3 and CeNi[subscript]12B[subscript]6. Discussions on the low temperature behaviors of these and other Ce intermetallic compounds are given.
