The influence of hydrostatic pressure on electrical resistance of a perovskite manganese oxide (La0.1, Ce0.4 Sr 0.5)MnO3 has been investigated under pressures up to 1.8 GPa in the temperature range of 77-320 K. With application of pressure, Curie temperature (Tc) increases at a rate of dTc/dp = + 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 (Tmax) shifts largely to lower temperature at a rate of dTmax/dp = -86K/GPa.
