چکیده
Interface engineering is an effective and feasible method to regulate the magnetic anisotropy of films by altering interfacial states between films. Using technique pulsed laser deposition, we prepared La 0.67 Sr 0.33 MnO 3 (LSMO) /SrCoO 2.5 (LSMO/SCO) on (110)-oriented 0.3 0.7 Al 0.65 Ta 0.35 O substrates. By covering SCO film above LSMO film, transformed easy magnetization axis from [001] [ 1 ¯ 0 ] in plane. Based statistical analyses, find that corresponding Mn–Mn ionic distances are different two types films, causing distortions Mn–O octahedron LSMO. In addition, it also induces diverse electronic occupation Mn 3+ ions. The e g electron occupies z 2 – r x y orbitals LSMO/SCO, respectively. We conclude spin reorientation leads transformation

Perpendicular magnetic anisotropy induced by tetragonal distortion of FeCo alloy films grown on Pd(001).
We grew tetragonally distorted FexCo1-x alloy films on Pd(001). Theoretical first-principles calculations for such films predicted a high saturation magnetization and a high uniaxial magnetic anisotropy energy for specific values of the lattice distortion c/a and the alloy composition x. The magnetic anisotropy was investigated using the magneto-optical Kerr effect. An out-of-plane easy axis of...
متن کاملOscillatory magnetic anisotropy originating from quantum well states in Fe films.
The magnetic anisotropy of Fe film grown on vicinal Ag(1,1,10) surfaces was studied with the in situ magneto-optic Kerr effect. Below 200 K, strong oscillations of the uniaxial magnetic anisotropy as a function of Fe thickness with a period of 5.7 monolayers are found, which can even cause the easy magnetization axis to oscillate between perpendicular and parallel to the steps. Such novel oscil...
