釔鐵石榴石單晶磁性薄膜磁特性的測量方法We have found the best ways to optimize the growth of quality zno films and got highly c - axis oriented zno films. the microstructures of the films were observed by afm. after analyzing the crystal structures, the crystal tropism and the surface conformation flatness, we found the result that the substrate temperature of 400 ? is ideal for silicon substrates, which conforms to the result of the structure analyse. by analyzing the magnetism of zno films, we found that the films appropriately doped with fe, co ions have magnetism at room temperature and their magnetism can be improved by doping other little cu ion, but it is not certain that the content of cu is higher, the film has more magnetism, so it has the best content of cu. moreover, the films which have best crystal structures may not have the best magnetism
