Abstract
【解決手段】垂直磁気異方性多層薄膜は、第1Pt/CoFeSiB層と前記第1Pt/CoFeSiB層上に形成された第2Pt/CoFeSiB層とを含む。
【選択図】図1
Description
また、これ以外に、このような磁気異方性多層薄膜構造と異なる実施の形態、または構成要素の変更、追加などによる他の実施の形態の提供が可能である。
すなわち、例えば本発明は以下の態様の、垂直磁気異方性多層薄膜及び垂直磁気トンネル接合構造を含む。
(2)前項1のCoFeSiB層が、Co84.8Fe5.96Si6.24B3.04〜Co70.5Fe4.5Si15B10の組成で構成されている上記に記載の垂直磁気異方性多層薄膜。
(3)前記第1Pt/CoFeSiB層及び前記第2Pt/CoFeSiB層の厚さの比が、1:1である前項1に記載の垂直磁気異方性多層薄膜。
(4)前記第2Pt/CoFeSiB層上に形成された第3Pt/CoFeSiB層をさらに含む前項1に記載の垂直磁気異方性多層薄膜。
(5)前記第3Pt/CoFeSiB層上に形成された第4Pt/CoFeSiB層をさらに含む前項4に記載の垂直磁気異方性多層薄膜。
(6)前記垂直磁気異方性多層薄膜の保磁力が20Oe以下である前項5に記載の垂直磁気異方性多層薄膜。
(7)前記垂直磁気異方性多層薄膜において、Pt厚さが8Åの場合、CoFeSiB厚さが3Å以下である前項5に記載の垂直磁気異方性多層薄膜。
(8)前記垂直磁気異方性多層薄膜において、CoFeSiB厚さが3Åの場合、Pt厚さが14Å以上である前項5に記載の垂直磁気異方性多層薄膜。
(9)非磁性間層(トンネルバリヤ)により分離されている自由層と固定層を含む磁気トンネル接合構造において、
前記自由層が、第1Pt/CoFeSiB層と前記第1Pt/CoFeSiB層上に形成された第2Pt/CoFeSiB層とを含むことを特徴とする垂直磁気トンネル接合構造。
(10)前記CoFeSiB層が、Co84.8Fe5.96Si6.24B3.04〜Co70.5Fe4.5Si15B10の組成で構成されている前項9に記載の垂直磁気トンネル接合構造。
(11)前記第1Pt/CoFeSiB層及び前記第2Pt/CoFeSiB層の厚さの比が、1:1である前項9に記載の垂直磁気トンネル接合構造。
図1に示すように、本発明で一実施の形態として形成した垂直磁気異方性薄膜の厚さを示すと、Si/SiO2 /Ta 50/Pt 4/[Pt(t1)/CoFeSiB(t2)]×n/Ta 50(厚さ単位:Å)である。ここで、nはPt(t1)/CoFeSiB(t2)層の個数(繰り返し回数)を意味し、t1はPtの厚さ、t2はCoFeSiBの厚さを意味する。Siは基板を意味し、SiO2は基板上に形成した酸化層であって、厚さは意味がない。
図2は、同じ構造と薄膜厚からなる既存の[Co/Pt]多層薄膜と本発明の[CoFeSiB/Pt]多層薄膜との磁気的特性を比較した図である。すなわち、薄膜構造は、Si/SiO2/Ta 50/Pt 4/[Pt 8/CoFeSiBまたはCo 3]×5/Ta 50(厚さ単位:Å)であり、磁気的特性は、VSM(vibrating sample magnetometer)で測定した。
