Abstract [en]

This paper discusses the effect of hydrostatic pressure up to 0.8 GPa on magnetic properties of manganites La0.7Ca0.3 - xSrxMnO3 (0 x 0.3, x = 0.03) and magnetoresistance data in an applied magnetic field of 5.0 T. Application of pressure enlarges the temperature range of the ferromagnetic phase. Curie temperature, TC, as a function of pressure and the temperature of resistance maximum, Tp, showed an anomaly for x = 0.15. The slope of pressure dependence of TC for x < 0.15 and x > 0.15 is higher than for x = 0.15. Dependence of temperature Tp on x consists of two curves: for x 0.15 and for x 0.15. There is a sharp bend on the Tp curve at x = 0.15. The structural phase transition from orthorhombic phase (x < 0.15) to rhombohedral one (x 0.15) corresponds to that concentration.
