摘要：
La-Zn doped M type Sr-ferrite thin films with various doping concentration were prepared by conventional rf diode sputtering. La-Zn doping reduces the grain growth rate, so that fine grains with mean grain size about 12nm were prepared with superior magnetic properties. It is found that suitable amount of La-Zn substitution may increase the M-s of the films, and modify the temperature coefficient of coercivity, while H-c increases with increasing concentration of La-Zn.
