A newly developed pressure setup for a.c. susceptibility measurements in the pressure range up to 2.0 GPa is presented; the temperature domain extends from 77 to 450 K. The steel pressure chamber contains the sample located at the center of a set of three compensated pick-up coils and the pressure and temperature sensors. Either alcohol or extraction naphtha is used as the liquid pressure transmitting medium. The (P,T) magnetic phase diagram of (Fe_0.975Ni_0.025)₂P system in the pressure range up to 2.0 GPa is reported.
