Influence of Argon Pressure on Texture and Microstructure of Cobalt Films Produced by Dc-Sputtering

Background and Objectives: The development of methods of textured Co film formation is of practical interest in the field of creating media with perpendicular recording of information or lateral spin-valve structures. Despite a rather wide study of the growth conditions effects on the microcrystalline structure of sputtered cobalt films, the possibility of changing the texture and microstructure via a change of the gas pressure has not been discussed.

Magnetic Properties of Textured NiFe(111) and NiFe(200) Films

Thickness dependencies (d м 20–370 nm) of the saturation magnetization 4πМ, the ferromagnetic resonance linewidth ΔH, the coercivity field Hc and the shape of hysteresis loops were investigated for Ni80Fe20 (NiFe) films with (200) texture. The thickness dependencies of magnetic parameters for NiFe(200) films were compared with the dependencies 4πМ(d), ΔH(d) and Hc(d) for NiFe(111) films with strong (111) texture and polycrystalline NiFe films.
