Magnetocaloric Effect: Direct Measurement
Original language description
We present the study of magnetocaloric effect of Gd60Mn40 alloy. This alloy was prepared from Gd and Mn of 3N purity. The stoichiometric mixture of these elements was melted in mono-arc furnace in ultra-high purity argon atmosphere and remelted several times to ensure homogeneity of the sample. The crystal structure of the sample was investigated by powder x-ray diffraction. We used the direct method to measure the adiabatic temperature change, ?T, and the magnetisation isotherms to calculate the isothermal entropy change, ?S. Direct measurement was performed in magnetic field of 4.7 T in temperature range from 261 to 307 K. We obtained the maximum temperature change ?Tmax = 3.5 K at 284 K. We measured temperature dependence of magnetisation in small magnetic field 0.03 T and evaluated the transition temperature TC = 289 K. We measured magnetic field dependence of magnetization in temperature range from 265 to 305 K in magnetic field up to 5 T and we evaluated the entropy change accord
