摘要：
A structural transition from the orthorhombic phase to the rhombohedral one is observed and investigated on a La0.8Ba0.2MnO3 single crystal. In the region of the coexistence of two phases, the effects of magnetic field (up to 12 T) and hydrostatic pressure (up to 5 kbar) on the temperature dependences of the electrical resistivity are studied. It is shown that magnetic field and pressure reduce the transition temperature and produce qualitatively similar effects on the electrical resistivity in the region of the structural transition.
