- Аннотация: The magnetocaloric effect Delta T has been studied by a direct method in two samples of the manganite Sm0.55Sr0.45MnO3, namely, a single crystal (sample A) and a ceramic sample (sample C). The temperature dependences of the Delta T effect of both samples exhibit a maximum at T (max) = 143.3 K for the sample A and T (max) = 143 K for the sample C. In these maxima, the values of the Delta T effect are 0.8 and 0.4 K in the magnetic field H = 14.2 kOe for the samples A and C, respectively. In addition, the Delta T(T) curve of the sample A has a minimum at T (min) = 120 K, in which Delta T = -0.1 K. The maximum value of the Delta T effect increases with an increase in the magnetic field H in the range of magnetic fields up to 14.2 kOe, and the rate of this increase at H > 8 kOe is higher than that at H < 8 kOe. These features of the Delta T effect are explained by the presence of ferromagnetic and antiferromagnetic A- and CE-type clusters in the samples.
