MAGNETO-RESISTIVE ELEMENT, THIN FILM MAGNETIC HEAD, AND THEIR MANUFACTURING METHODS

摘要

PROBLEM TO BE SOLVED: To provide an MR element securing high crystallinity at a tip of a magnetic domain control layer located in the vicinity of an MR laminate, a thin film magnetic head, a manufacturing method of the MR element, and a manufacturing method of the thin film magnetic head. SOLUTION: The MR element in which current flows in the vertical direction to a layered surface includes: a lower electrode layer; the MR laminate laminated on the lower electrode layer; a magnetic domain control bias layer located on both breadthwise sides of a track of the MR laminate and made of a material containing a hcp structure at least partially; a metallic layer formed to continuously cover the magnetic domain control bias layer and the MR laminate on them and made of a material having a bcc structure; and an upper electrode layer formed on the metallic layer.
