Carrier transport spin–orbit dynamics in surface enhanced Raman shift of perovskite films

Abstract The unknown LSMO/ZnO spin-orbit dynamics and bandgap are presented by Mn partial wave state density of LaSrMnO 3 and SRS spectroscopy. Raman active phonon in orthorhombic perovskite ZnO/La 0.7 Sr 0.3 MnO films are were focused by measuring Raman spectra in various scattering configurations. The LSMO spin state density is modified by Mn mixed valence state. The results show that the spin–orbit is caused by anomalies tilt of MnO 6 octahedron and electrons hopped into the empty orbital states. The transfer of d x 2 − y 2 orbits dynamics is in the background of the ferro-orbital order state of crystal stabilized d 3 z 2 − r 2 orbit effect. The LSMO/ZnO displays magnetic and phononic scattering measurement. The kinetic energy gain achieved by the orbital competition, magnetic ordering, strong crystal field and charge order of energy band splitting. The LSMO/ZnO junction exhibits excellent junction ​antiferromagnetic/ferromagnetic phonon peaks and magnetoresistance behavior over the temperature range of 77–300 K. The significant energy band competition originates from the strong crystal splitting field and orbital canting.
