摘要：
The polycrystalline bulk samples with nominal composition Zn1-x(Mn1/2Co1/2)(x)O (x = 10%, 15%,30%) were fabricated at 600 degrees C by the standard solid-state reaction method. The structural analysis shows that the lower doped samples (x < 15%) are single phase of wurtzite structure, while for the high-doped sample (x = 30%), beside the main peaks of wurtzite structure, the peaks of secondary phase are visible. Magnetization measurement indicates that all the samples show feffornagnetic ordering with T-c > 300 K. Based on the structural analyses, the experimental observation is discussed.
