Description	The crystal structure and complex twinning microstructure of epitaxial Ni–Mn–Ga films on (1 0 0) MgO substrates was studied by X-ray diffraction using 2θ scans, pole figure measurements and reciprocal space mapping (RSM). Above the martensitic transformation temperature the film consists of single austenite phase with lattice constant a = 5.81A at 419 K. At room temperature some epitaxially grown residual austenite with a = 5.79A remains at the interface with the substrate, followed by an intermediate layer exhibiting orthorhombic distortion, atrans = 6.05A, btrans = 5.87A, ctrans = 5.73A and a major fraction of 14M (7M) martensite, a = 6.16A, b = 5.79A, c = 5.48A. The seven-layered modulation of this metastable martensite structure is directly observed by RSM. The intermediate phase observed close to interface indicates the existence of an instable, pre-adaptive martensite phase with a short stacking period.
