抄録
The structural and magnetic properties of Co2Cr0.6Fe0.4Al (CCFA) thin films epitaxially grown on GaAs substrates by sputtering were investigated. The CCFA film directly grown on GaAs showed a cube-on-cube crystallographic relation, while it was rotated by 45 in the (0 0 1) plane when a thin MgO layer was inserted between the CCFA and GaAs. Both samples showed strong magnetic anisotropy, in which a uniaxial anisotropy with an easy axis of [110]GaAs or [1–10]GaAs dominated with a slight cubic anisotropy having easy axes of <110>CCFA superimposed. The uniaxial anisotropy constants were approximately 1.6 times as large as the cubic anisotropy constants for both samples.
