Abstract

The magnetic and phase properties of Co _xTi _1-xO ₂ anatase thin films grown epitaxially on (001) LaAlO ₃ were examined by a ractive rf magnetron cosputter deposition. It was shown that the Co _xTi _1-xO ₂ thin films exhibit room-temperature ferromagnetism by hysteresis in M-H loop. The examination of the surface mocrostrucutre of the film by field-emission scanning electron microscopy (FESEM) was also demonstrated. The surface surface segregation from Ti-Co-O particles in highly doped films was also observed.
