Abstract: Thin films of strontium ferromolybdate Sr2FeMoO6 are a promising material for spintronic applications. To comprehensively study the relationship between structure, electrophysical properties, and magnetic characteristics of films deposited by ion-beam sputtering on Al2O3 substrates followed by reductive annealing at 900°C, a set of modern microscopic and spectroscopic techniques was employed. Specifically, Raman spectroscopy, atomic force microscopy, conductive microscopy, Kelvin probe force microscopy, and magnetic force microscopy were used to investigate in detail how different annealing durations (0.5, 1, and 1.5 hours) affect key parameters of the material. It has been found that the duration of annealing significantly influences the surface roughness, electrophysical properties, and most importantly, the formation of magnetic domain structures in Sr2FeMoO6 films. Analysis of the obtained data revealed that optimal structural characteristics are achieved after annealing for 1 hour, while the best magnetic domain structure is observed in samples subjected to annealing for 1,5 hours. These results are important for optimizing the synthesis process of Sr2FeMoO6 films with improved characteristics, which contributes to more efficient use of this material in various spintronic devices.

Keywords: strontium ferromolybdate films, scanning probe microscopy, I-V characteristics, magnetic force microscopy
