Abstract

(Zn_1-xMn_x)O diluted magnetic semiconductors (DMSs) grown on (0001) Al₂O₃ substrates by radio frequency magnetron sputtering were investigated with the aim of producing a material with a high ferromagnetic transition temperature (T_c). X-ray diffraction, photoluminescence, and Hall-effect measurements showed that the grown (Zn_1-xMn_x)O thin films were p-type crystalline semiconductors with single phases. Magnetization curve as a function of magnetic field at 5K indicated that ferromagnetism existed in the (Zn _1-xMn_x)O thin films, and magnetization curve as a function of temperature showed that the T_c of the (Zn _0.93Mn₃0.07)O thin film was 70K. These observations can improve the understanding of the increase in T_c for (Zn _1-xMn_xO DMSs grown on (0001) Al₂O₃ substrates.
