抄録
内容記述 MBE法によりMgO(001)基板上にFePt-Ag合金膜を作製し,その結晶および表面構造と垂直磁気異方性の関係を調べた.また,FePtと同じ結晶構造を持つが規則・不規則変態温度の低いFePdについても同様の検討を行い,FePtの結果と比較した.FePtにAgを20at.%添加することで,グラニュラー化およびL1_0規則化温度の低減に有効であることが分かった.また,これに伴い,FePtではAg添加により保磁力および垂直磁気異方性の増大が観測された.一方FePdではAg添加によりグラニュラー構造から連続膜に変化し,保磁力,磁気異方性も低下した.FePt-Ag alloy films were prepared on MgO(001) substrates by an MBE method, and their crystal, surface structures and perpendicular magnetic anisotropies were investigated. Moreover, the same experiments were performed for FePd alloy, films which have the same crystal structure as FePt while exhibit much lower order-disorder transition temperature than that of FePt, and the results obtained for the twosystems were compared. In the case of FePt system, the Ag addition with the amount of 20 at.% was effective to promote the granular structure and lower the ordering temperature. These results were consistent with the increase of the coercivity and perpendicular anisotropy by the addition of Ag in FePt. On the other hand, the structure of FePd varied from granular to continuous film by adding Ag, accompanying the reduction of its coercivity and perpendicular anisotropy.
