Perpendicular magnetic write head and magnetic recording device
A trailing shield is provided on a trailing side of a magnetic pole with a non-magnetic gap layer in between, and an intermediate layer having negative uniaxial magnetocrystalline anisotropy is provided between the non-magnetic gap layer and the trailing shield. The intermediate layer has a magnetic property in which an easy axis of magnetization is provided in an in-plane direction and thus magnetization is likely to occur in that direction, whereas a difficult axis of magnetization is provided in a direction intersecting the in-plane direction and thus magnetization is less likely to occur in that direction. Accordingly, magnetic flux becomes difficult to excessively flow from the magnetic pole into the trailing shield.
