Popis: The heat capacity (C P), the thermal diffusion (η), the thermal conductivity (κ), and the electrical resistance of the La0.825Sr0.175MnO3 single crystal have been measured in the temperature range 80–350 K in magnetic fields to 40 kOe. Dependences C P(T), κ(T), and η(T) have anomalies near T C, which are suppressed in magnetic field. The minima in dependences κ(T) and η(T) near T C are explained by the phonon scattering on fluctuations of the magnetic order parameter. Dependences κ(T) and η(T) have anomalies near T S = 200 K related to the structural transition from the rhombohedral (R) to the orthorhombic (O*) phase.
