Abstract:
Investigation of the temperature and magnetic-field dependences of the electrical conductivity and the velocity and damping of the transverse ultrasonic waves at a frequency of 770 MHz revealed the temperature and magnetic hysteresises of the elastic parameters and the electrical resistivity. This is explained by the influence of magnetization on the structural phase transition in a manganite sample. The two-phase crystal structure influences the magnetization process and the behavior of resistivity in the vicinity of the concentrational intersection of the magnetic and structural phase transitions.
