EN

The structural phase transition from tetragonal to triclinic structure in CePd₂Ga₂ compound was studied by means of electrical resistivity measurement under hydrostatic pressure. The shift of the transition to the higher temperature with increasing pressure was revealed: 195 K in 3 GPa compared to 125 K in ambient pressure.
