In this paper, the magnetic properties of p-type Zn1-xMnxO powders are reported. This are prepared from the decomposition of an oxalate precursor Zn1-xMnxC2O4.H2O. The oxalate precursor is obtained by coprecipitation of 50 ml of a 0.4mol/L aqueous solution of Zn and Mn acetates and the same volume of a 0.4 mol/L solution of oxalic acid.
