A La0.7Sr0.3MnO3 thin film epitaxially grown on a LaAlO3 (001) substrate by pulsed laser deposition has been investigated by means of low-temperature magnetic force microscopy under high stability conditions. The ferromagnetic film exhibits a stress-induced perpendicular easy axis of magnetization. The domain structure was imaged at zero field after (i) thermal demagnetization, (ii) saturation in an in-plane field and (iii) saturation in an out-of-plane magnetic field, respectively. Stripe domains were observed in all cases, however, contrast and domain width are increased after out-of-plane saturation while alignment of stripe domains in field direction occurs after in-plane saturation. A quantitative analysis of the image contrast suggests a variable in-plane component of the magnetization, dependent on the magnetic history of the sample. Calculations of domain width and contrast from the relevant energy contributions are compared with experimental results.
