The soft magnetic properties of FeCo films, sandwiched by thin NiFe or NiFeCr films, are discussed in relation to the microstructure. Ta/NiFe(Cr)(5 nm)/FeCo(100 nm)/ NiFe(Cr)(5 nm)/Ta films prepared using the UHV sputtering process with pure Ar plasma show bcc-(110) preferred grain orientation of FeCo layer with the 110 direction sharply perpendicular to the film plane, resulting in soft magnetic properties. No significant difference in soft magnetic properties was observed by the use of nonmagnetic NiFeCr layers instead the NiFe layers, moreover, by varying FeCo composition between 25 and 30 at%Co. The best thickness of the FeCo layer in order to realize soft magnetic properties was found to be 100 nm in the present study, with a high saturation magnetization of 2.3 T. An addition of N 2 gas to Ar plasma during film deposition did not lead to an improvement of the soft magnetic properties. A film of [FeCo(100 nm)/NiFe(5 nm)] 4 layer structure was subjected to the fabrication of single-pole-type recording head, and it is successfully demonstrated that the film has a sufficient softness to be used for the recording head application.

“…There is a growing demand of magnetic thin film materials for high-radio-frequency (GHz) use: magnetic recording heads, integrated thin-film inductors, and electromagnetic noise absorbers [1][2][3][4][5][6]. In integrated inductors, ferromagnetic thin film materials can be incorporated in the inductors to boost their inductance and enhance their quality factor [7].…”

“…Fe-Co-based sputtered films have been investigated as a promising candidate with a high B s of more than 2.4 T [1,2]. We have reported that the combination of a small amount of Al 2 O 3 addition and a thin underlayer film is important to obtain small H ch (H c in the hard axis direction) less than 1 Oe with a high B s of 2.4 T in a wide range of film thicknesses for Fe-Co films [3].…”
