Abstract
The effect of gas flow on Sr2FeMoO6 thin films during pulsed laser deposition was investigated by characterizing their structural and magnetic properties. Crystallographic results reveal a great amount of structural distortion in films fabricated with high Ar or Ar + 5% H-2 flow rate. The films with structural distortion have also larger coercive field, demonstrating domain pinning. The same films show also higher Curie temperature and saturation magnetization. Our results indicate that, in addition to other optimal deposition parameters, adjusting gas flow can be used for fine adjustment of Sr2FeMoO6 films for spintronic applications.
