- Microstructure and magnetic properties of FeCo epitaxial thin films grown on MgO single-crystal substrates. Shikada, Kouhei; Ohtake, Mitsuru; Kirino, Fumiyoshi; Futamoto, Masaaki // Journal of Applied Physics;Apr2009, Vol. 105 Issue 7, p07C303
FeCo epitaxial films were prepared on MgO(100), MgO(110), and MgO(111) substrates by ultrahigh vacuum molecular beam epitaxy. FeCo thin films with (100), (211), and (110) planes parallel to the substrate surface grow on respective MgO substrates. FeCo/MgO interface structures are studied by...
- Study of the dynamic magnetic properties of soft CoFeB films. Bilzer, C.; Devolder, T.; Kim, Joo-Von; Counil, G.; Chappert, C.; Cardoso, S.; Freitas, P. P. // Journal of Applied Physics;9/1/2006, Vol. 100 Issue 5, p053903
We study the magnetization damping in ion-beam deposited Co72Fe18B10 thin films as a function of film thickness and crystalline state. As-deposited amorphous layers showed low damping (Î±app=0.006) that is thickness independent. 40 nm Co80Fe20 with no boron content exhibited a value twice...
