Abstract: We prepared the pulsed laser deposited Fe:LaSrFeO4 (LSFO) composite films on quartz substrates by decomposing the La0.5Sr0.5FeO3 target at room temperature in a high vacuum. Impacts of anneal temperature on the structural and physical properties have been investigated, and the systematic changes were found in structural, magnetic and optical absorption properties upon annealing. The LSFO (110) spacing decreases with the increase of annealing temperature, which can be attributed to the release of intrinsic strain; and there is an increase in spacing for the 750∘C annealed sample, which is ascribed to the oxygen loss in LSFO films.
