Abstract

Raman active phonon in orthorhombic perovskite La 0.7 Sr 0.3 MnO films and ZnO/LSMO multi films were focused by measuring Raman spectra of 325 nm and 512nm laser in scattering configurations. The results sho w that the spin orbit is caused by anomalies tilt of MnO 6 octahedron . The transfer of d x2y2 orbits dynamics is in the background of the ferro orbital order state of crystal stabilized d 3z2 r 2 orbit effect. The kinetic energy gain achieved by the orbital c ompetition, strong crystal field and charge order of energy band splitting. The LSMO/ZnO junction exhibits excellent junction behavior over the temperature range of 77 300 K..
