Аннотация
The temperature dependences of the velocity of longitudinal sound and internal friction in the ferromagnetic La0.5Pr0.2Ca0.3MnO3 single crystal with magnetic first-order phase transition were studied. It was found that the sound velocity decreases by ≈20% in transition from the ferromagnetic to paramagnetic state. In the paramagnetic region, the extended temperature hysteresis of the sound velocity and the internal friction was observed. It was shown that La0.5Pr0.2Ca0.3MnO3 has two paramagnetic phases with different sound velocities.
