Magnetic study of nanocrystalline 0.95MnO/0.05ZnO

► Magnetic properties of 0.95MnO/0.05ZnO have been studied by dc magnetization and magnetic resonance. ► FMR and EPR spectra were identified and attributed to various spin systems. ► From the spread of blocking temperatures obtained from magnetic resonance the spread of nanoparticles sizes was estimated.
