Description
We have studied the electrical resistivity in a skutterudite compound PrFe4P12 under high pressure. An antiferro-quadrupolar ordering temperature TQ decreases monotonously with increasing pressure up to 2.4GPa. Above 2.4GPa, the metal-insulator (M-I) transition appears. By applying magnetic field, this M-I transition is suppressed easily and heavy-fermion state is realized. The observed Kondo effect and the field-induced heavy-fermion state at high pressure suggest that the quadrupolar interactions of the f electrons of Pr3+ survive even in the insulator phase
