Abstract
The double perovskite Sr 2 CrReO 6 is an interesting material for spintronics, showing ferrimagnetism up to 635 K with a predicted high spin polarization of ≈ 86 % . We fabricated Sr 2 CrReO 6 epitaxial films by pulsed laser deposition on (0 0 1)-oriented SrTiO 3 substrates. Phase-pure films with optimum crystallographic and magnetic properties were obtained by growing at a substrate temperature of 700 ∘ C in pure O 2 of 6.6 × 10 - 4 mbar . The films are c -axis oriented, coherently strained, and show less than 20% anti-site defects. The magnetization curves reveal high saturation magnetization of 0.8 μ B /formula unit and high coercivity of 1.1 T, as well as a strong magnetic anisotropy.
