Abstract

High moment CoFe films on thin NiFe underlayers N.X. Sun, J. Jarratt, and R. Hsiao In this work, we disclose high saturation magnetization soft magnetic films, the NiFe seeded CoFe films with Co in the range of 30~40at%. The NiFe seeded CoFe films have a high saturation magnetization, low coercivity, decent corrosion resistance and thermal stability, and are adopted as the process record for our new products as the Pole cap (P1cap) layer of films.
