Zn1-xMnxO layers with x varying between 0.006 and 0.22, have been prepared by metal-organic chemical-vapor deposition technique and analyzed by electron paramagnetic 2, resonance spectroscopy. The layers show an exchange narrowed single line spectrum of Mn2+ ions; its temperature dependence demonstrates antiferromagnetic coupling with an effective exchange constant of J1/k(B)=-14.9 K.
