Abstract
The distinct Raman active phonon s in orthorhombic LSMO films heterojunctions were present by Raman spectr oscopy of
325 nm and 512nm laser by the spin orbit lattice dependence of frequency performances in scattering configurations. The
resul ts show that high frequency mode structure and the perovskite symmetry phonon peaks is caused by anomalies tilt of
Mn O 6 octahedron . The spin orbit transfer of d x2y2 orbits dynamics is based on crystal structure stabilized d 3z2 r 2 orbit. The
dynamics energ y gain achieved by the ferro orbital ordering, strong crystal field , spin orbital competition a nd charge order of
energy band splitting. The LSMO/ZnO junction display excellent junction behavior over the temperature range of 77 300 K
and exhibit the strong crystal field and orbital canting.
