摘要：
A magnetoresistive effect (MR) element, a thin-film magnetic head having the MR element, a method for manufacturing the MR element, and a method for manufacturing the thin-film magnetic head are disclosed. The MR element, which uses electric current in a direction perpendicular to layer planes, includes a lower electrode layer, a MR multilayered structure formed on the lower electrode layer, a magnetic domain controlling bias layer that is disposed on both sides of the MR multilayered structure along the track-width direction and is made of a material at least partially including an hcp structure, a metal layer made of a material having a bcc structure formed on the magnetic domain controlling bias layer and the MR multilayered structure to cover the magnetic domain controlling bias layer and the MR multilayered structure, and an upper electrode layer formed on the metal layer.
