Abstract

We report the low temperature magnetization and specific heat of single-crystal Pr₅Si₃ at ambient pressure under magnetic field up to 9 T and temperatures down to 3 K. Pr₅Si₃ orders ferromagnetically below T_C = 43 K. The ferromagnetic state is strongly anisotropic where the basal plane in the body-centered tetragonal crystal structure is the easy-magnetic plane. Under hydrostatic pressures up to 18 kbar the magnetization for temperatures down to 3 K and magnetic fields up to 9 T shows only a weak variation of the ordered moment and T_C. Magnetization loops at low magnetic fields show changes of the hysteresis loops, notably the emergence of shoulder at the coercive field, that are characteristic of a ferrimagnetic modulation that is stabilized under pressure.
