Magnetic phase transition characteristic in La0.7Sr0.3MnO3/Ta2O5composites with different grain size was investigated in this work. There were double maxima in |dM/dT|–T curves for the composites with grain size in the range of 100–200nm sintered at relative low temperature for short time, which indicated that two paramagnetic–ferromagnetic (PM–FM) transitions happened. The PM–FM transition temperatures of Tc1and Tc2were the contribution of grain boundary and grain, respectively. Tc1varied with Ta2O5content and sintering condition, whereas Tc2remained almost the same value. For the composites with grain size larger than 500nm sintered at high temperature for long time, single magnetic phase transition behavior was observed.
