High-pressure studies of Kondo-like perovskite (La0.1Ce0.4Sr0.5)MnO3

Abstract The influence of hydrostatic pressure on electrical resistance of a perovskite manganese oxide (La 0.1 Ce 0.4 Sr 0.5 )MnO 3 has been investigated under pressures up to 1.8 GPa in the temperature range of 77–320 K. With application of pressure, Curie temperature ( T C ) increases at a rate of d T C /d p =+1.9 K/GPa . It is also found that the coefficient of −log T term originated from Kondo-like effect decreases with increasing pressure and the resistance maximum temperature ( T max ) shifts largely to lower temperature at a rate of d T max /d p =−86 K/GPa .
