Textured growth of CoFe for soft underlayers in CoCrPt:SiO2 perpendicular magnetic recording media

Ru/FeCoB crystalline soft magnetic underlayers with high anisotropy field for CoPtCr–SiO2 granular perpendicular magnetic recording media

“…At high concentration of Co, FeCo is in fcc phase. 9 Since a fcc ͑111͒ or a hcp ͑001͒ texture is suitable to align ͑001͒ plane of Co-based alloys, promotion of the hcp-Ru ͑001͒ orientation by the fcc-FeCo ͑111͒ is rational. In our case, FeCo is in bcc phase.…”

Recording media research for future hard disk drives

“…The most promising approach to reduce the intermediate layer thickness involves using a crystalline SUL [25][26][27][28]. By using suitable combination of seedlayers, such as Ta/Ru or CrTi/Pd, an fcc-based SUL such as FeCo could grow with a very good fcc(111) texture.…”

Interface influence on the properties of Co 90 Fe 10 films on soft magnetic underlayers – Magnetostrictive and Mössbauer spectrometry studies

“…Thus Zr strongly influenced the texture and magnetic properties of Co 90 Fe 10 films. Piramanayagam et al [8] studied the effect of Ta and Pd underlayers on 40nm Co 90 Fe 10 films. They found that growing on Ta reduced the coercive field by a factor 5, due to a change in texture of the films.…”
