Abstract: The layered magnetic film has high saturation magnetic flux density and superior soft magnetic characteristics and can be used as a material of a write-head of a magnetic head capable of recording data with high recording density. The layered magnetic film comprises: at least one magnetic layer mainly made of iron (Fe) and cobalt (Co); and at least one NiFe layer, the magnetic layer and the NiFe layer are alternately layered, and the NiFe layer is a discontinuous film.

Abstract: The soft magnetic film has superior soft magnetic characteristics and is suitable for a thin film magnetic head. The soft magnetic film of the present invention comprises: a magnetic base layer including a ferromagnetic element; and a ferromagnetic layer being piled on the magnetic base layer. The soft magnetic film has uniaxial magnetic anisotropy. The magnetic base layer includes at least one element selected from Fe, Ni and Co as the ferromagnetic element.

Abstract: The present invention relates to a magnetic thin film, which has high saturation magnetic flux density Bs of 2.2T or more, which is formed into a flat surface having surface roughness of 5 nm or less and which is capable of preferably being used for a write-head, and a magnetic head. The magnetic thin film includes a FeCo-based alloy layer stacked with a different layer so as to obtain the surface roughness of 5 nm or less. When forming the FeCo-based alloy layer, it is possible to flatten the film surface by performing reactive spattering using a reaction gas such as N2 for each of the layers forming the multi-layered thin film.
