Abstract: Structural, morphological and EPR investigations on Zn<subscript>1-x</subscript>Mn<subscript>x</subscript>O fine ceramics (x = 0.01 and 0.03) are reported. XRD studies reveal a wurzite-type structure, while the formation of ZnMnO<subscript>3</subscript> secondary phase was evidenced only for x = 0.03 sample. Both EPR spectra present a hyperfine structure specific to isolated Mn<superscript>2+</superscript> ions and for the sample x = 0.03, a new quite broad resonance line arises, which could be attributed to a ferromagnetic phase.
