中文摘要Magnetization, resistivity, and specific heat were studied systematically in the absence and presence of magnetic field in Pr0.7Pb0.3MnO3 single crystals, in which electronic phase separation occurs near the ferromagnetic/metallic-paramagnetic/insulating phase transition and the metal-insulator transition temperature is much higher than the Curie temperature. These measurements allow us to extract some fundamental physical parameters such as Fermi energy, density of states at the Fermi energy, Debye temperature, and interaction among electrons, phonons, and magnons. Furthermore, the magnetic entropy was studied around the phase transition temperature regime. It was found that a magnetic entropy change associated with the transition from the connected ferromagnetic phase to isolated superparamagnetic clusters appeared near the metal-insulator transition temperature following a large magnetic entropy change near the ferromagnetic-paramagnetic phase transition.
