Pressure effects of susceptibility and specific heat in PrCu2

Abstract The pressure effects on magnetic susceptibility, specific heat and the co-operative Jahn–Teller transition temperature, T JT , in the single crystalline sample are presented. At P =1.2 GPa susceptibility shows remarkable maximum at T = T max while specific heat shows no anomalous change around T max . However, at T ⪡ T JT the upturn of nuclear specific heat is developed with pressure. Our findings imply that a magnetic ordering is induced by pressure.
