摘要：

The effect of microstructure and the frequency of change in an alternating magnetic field on the adiabatic temperature change Delta T-ad in manganite Pr0.7Sr0.2Ca0.1MnO3 has been studied. It has been shown that the transformation of specimens from a denser to looser microstructure leads to both a decrease in Delta T-ad and a stronger frequency dependence of the adiabatic temperature change. For the specimen with an annealing temperature of 1300 degrees C, Delta T-ad is 0.6 K at a frequency of 1 Hz in a field of 1.2 T to decrease to 0.3 K at 20 Hz (by more than 50%). For the specimen with an annealing temperature of 600 degrees C, Delta T-ad is 0.45 and 0.06 K at frequencies of 1 and 20 Hz, respectively (i.e., decreases by more than 80%).
