The present invention provides a spin-valve type thin film magnetic element
that is able to certainly align the magnetization direction of the free
magnetic layer in one direction by improving the exchange coupling
magnetic field generated between the bias layers and ferromagnetic layer,
and is able to reduce the thickness of the bias layer to be smaller than
the thickness of the bias layer of the conventional spin-valve type thin
film magnetic element for obtaining the same magnitude of the exchange
coupling magnetic layer as that in the conventional spin-valve type thin
film magnetic element.
