Abstract CuO is considered as an excellent candidate for numerous applications including in optical and electronic devices because of its unique physical properties such as low resistivity, oxygen vacancy mediated room temperature ferromagnetism, and low bandgap. Here, the role of additional Mn doping on the electronic and magnetic properties of Cu0.945Fe0.055-xMnxO has been investigated. Le Bail profile analysis of x-ray diffraction data emphasizes on the single-phase monoclinic C2/c symmetry for all samples. The Mn addition in Cu0.945Fe0.055O modifies the magnetic properties. Highest saturation moment is observed for x = 0.012 sample. X-ray absorption studies hint at a proper substitution of Mn4+ and Fe3+ ions in CuO and emphasize on the intrinsic origin of ferromagnetism in all the samples.
