概要
- 論文の詳細を見る
La-Zn substituted M type strontium ferrite thin films were prepared by reactive rf diode sputtering. The structure, surface morphology, magnetic properties and their temperature dependence were investigated. It was found that La-Zn substitution reduces the grain growth rate, so that it was possible to obtain films with mean grain size about 12 nm. Suitable amount of La-Zn substitution increases the saturation magnetization Ms, the magnetocrystalline anisotropy constant K_1 and coercivity Hc of the films. La-Zn substitution improves also the temperature coefficient of coercivity of the films.
