Abstract

Structural study on the photo-switching system Pr_0.55 (Ca_1-ySr_y)_0.45 MnO₃ thin films on perovskite (011) substrate has been made with synchrotron radiation diffraction experiment. The insulating phase of y=0.20 sample was found to be an antiferro-orbital ordered phase with large lattice distortion and the ferromagnetic metallic phase of y=0.40 film show no distinct lattice distortion from the paramagnetic phase, which are very similar with (Nd,Pr)_0.5Sr_0.5MnO₃ films. A striking contrast of the orbital ordered phase of y=0.20 film to (Nd,Pr)_0.5Sr_0.5MnO₃ films was its untwinned structure.
