Sm-Co film; huge coercivity; phase transition; microstructure
We have investigated the influence of composition and annealing conditions on the magnetic properties and microstructural features of SmCox films that were prepared by sputtering and subsequent annealing. A huge in-plane coercivity of 5.6 T was obtained from an optimally annealed Sm-Co film which was attributed to the nanometer sized polycrystalline microstructure of the highly anisotropic SmCo5 phase. Although a high density of planar defects were observed in the films that were annealed at high temperatures, they did not act as strong pinning sites for domain wall motion. The effect of Cu on [SmCo4.5(9 nm)/Cu(xnm)](10) multilayer thin films was also studied. An appropriate Cu content increased the coercivity. (c) 2006 Elsevier B.V. All rights reserved.
