Pr0.7Sr0.3MnO3/La0.5Ca0.5MnO3/Pr0.7Sr0.3MnO3(PSMO/LCMO/PSMO) trilayers were deposited on(001)-oriented single crystal MgO by pulsed laser deposition.The thickness of both PSMO layers was 36 nm while the thickness of LCMO layer was 6

respectively.Out-of-plane and in-plane lattice parameters of trilayers were obtained by using symmetric scanning and asymmetric scanning mode of high resolution X-ray diffraction.Strain states of trilayers have been studied.The results showed that strain relaxation states of trilayers were decided by bulk strain and Jahn-Teller(JT) strain together.The mechanism for strain relaxation in trilayers is different from that for tetragonal distortion.The competition between bulk strain and Jahn-Teller(JT) strain played an important role in the magnetotransport and magnetic properties of trilayers.
