Abstract
Magnetostriction measurements were performed for stoichiometric La1−xSrxMnO3 samples with x=0.11, 0.13, and 0.165 in magnetic fields to 12 T. By combining temperature and magnetic field dependent magnetostriction data with magnetization and resistivity results, the complex relationship between structural and physical properties was clarified. In the paramagnetic phase, large magnetic fields suppress a transition near x=0.13 from a structure with disordered Jahn–Teller (JT) orbital ordering (O*) to a structure with large coherent JT orbital ordering (O′), and near x=0.165 remove a transition from a structure with no coherent JT orbital ordering (R) to O*. The reentrant structural transition from O′ to O* appears between ferromagnetic and spin–canting transitions for x=0.11 and 0.13; temperatures of all transitions increase with magnetic field. The low temperature structural O* to O′ transition in the ferromagnetic phase for x=0.165 remains unchanged by application of an external magnetic field.
