Fig. 1: Crystal structure and surface morphology of Co2MnGa.

a θ–2θ scan, the inset is the rocking curve from (004) peak, and b in-plane φ scans from −45° to 315°, for 50 nm Co2MnGa thin films. c X-ray reflectivity for the 20 nm Co2MnGa thin film, the inset is the atomic force microscopy image (5 × 5 µm2) with colour contrast (dark to bright) for the height scale corresponds to 3.5 nm. The scale bar corresponds to 1 μm.
