Abstract

Specific heat and effect of pressure on the electrical resistivity of CePtGa single crystal have been measured upto 30 kbar. A sharp peak in the ratio of specific heat to temperature and in electrical resistivity is observed at 3.3 and 3.5 K, respectively, which is ascribed to an antiferromagnetic transition. The results reveal that T_N decreases linearly with increasing pressure upto 30 kbar.
