Magnetoinduced structural, Jahn–Teller, dielectric, and transport effects in La0.875Sr0.125MnO3

The temperature and magnetic field dependences of elastic moduli and resistance are studied in a La0.875Sr0.125MnO3 single crystal. In addition to the metal–insulator transition, the structural transition from the cooperative J–T strongly distorted orthorhombic phase to the charge ordering phase is studied at T J–T = 150 K in magnetic fields of up to 2 T. Results show it is possible to control the acoustic parameters in the vicinity of T J–T via magnetic fields.
