Electron microscopy is used to reveal the competitive epitaxial growth of bcc structure (Cr1−xMnx)5Al8 and (Cr1−yMny)2AlC [Mn+1AXn (MAX)] phase during both magnetron sputtering and arc deposition. X-ray diffraction θ–2θ measurements display identical peak positions of (000n)-oriented MAX phase and (Cr1−xMnx)5Al8, due to the interplanar spacing of (Cr1−xMnx)5Al8 that matches exactly half a unit cell of (Cr1−yMny)2AlC. Vibrating sample magnetometry shows that a thin film exclusively consisting of (Cr1−xMnx)5Al8 exhibits a magnetic response, implying that the potential presence of this phase needs to be taken into consideration when evaluating the magnetic properties of (Cr, Mn)2AlC.
