films are grown on different substrates with pulse laser deposition. In addition to the regular magnetization and transportation measurements, ferromagnetic resonance technique is applied to investigate the internal field of PSMO films. In cooperated with magnetization and high resolution X-ray diffraction, the distinct magnetic and electronic transport behaviors are attributed to the strain modulated orientations of laminar FM layer because of the interfacial strain.
