中文摘要	we have investigated the magnetic properties of co-doped zinc oxide (zno) film deposited on silicon substrate by magnetron sputtering. co ions have a valence of 2+ and substitute for zn sites in the lattice. by using a chemical etching method, an extrinsic ferromagnetism was demonstrated. the observed ferromagnetism is neither associated with magnetic precipitates nor with contamination, but originates from the silicon/silicon oxide interface. this interface ferromagnetism is characterized by being temperature independent and by having a parallel magnetic anisotropy.
