A CPP type magnetic sensing element capable of properly performing magnetization
control of a free magnetic layer and having small hysteresis and an excellent playback
characteristic, as well as a manufacturing method therefor, are provided. Second
antiferromagnetic layers are provided not only on both edge sections of the free
magnetic layer, but also on the middle rear end. In the height-side edge of the
middle front end of the aforementioned free magnetic layer, a sense current magnetic
field in the direction opposite to the magnetization direction of the aforementioned
free magnetic layer is cancelled by a bias magnetic field from the second antiferromagnetic
layer provided on the middle rear end. Consequently, an influence of the aforementioned
sense current magnetic field can be reduced, turbulence in the magnetization of
the aforementioned free magnetic layer can be made smaller than ever, and a magnetic
sensing element having small hysteresis can be manufactured.
