Abstract

Magnetic properties of amorphous Co-Fe-Ta-B thin films are investigated. A tailorable spin reorientation transition (SRT) from in-plane single-domain-like state to out-of-plane multidomain state with increasing film thickness and temperature is obtained up to ∼2.5 μm thick films, in contrast to previously reported ultrathin ferromagnetic films of transition metals consisting of about half a dozen of monolayers. Atomic relaxation is shown to have significant influence on the SRT. Our results showed that the atomic randomness and the strains are responsible for the SRT in magnetic materials.
