摘要
The specific heat, thermal diffusivity, and thermal conductivity of ceramic samples of Nd0.55Sr0.45MnO3, Sm0.55Sr0.45MnO3, and Eu0.55Sr0.45MnO3 in the temperature range 20-350 K have been measured. Anomalies due to magnetic phase transitions have been observed and are interpreted. The temperature dependence of the free-path length is traced. The dependence of the measured coefficients on the degree of cationic disorder due to the difference of the radii of the A cations is determined.
