METHOD OF MANUFACTURING MAGNETORESISTIVE EFFECT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a novel method of manufacturing a magnetoresistive effect element having sufficiently high power. SOLUTION: After a second magnetizing step of fixing and pinning the magnetizing direction of a first magnetic layer 3 constituting a pinned layer of a magnetoresistive effect element, or after a first and third magnetizing steps of magnetizing a second magnetic layer 5 constituting a free layer of the magnetoresistive effect element approximately perpendicular to the magnetizing direction of the first magnetic layer, a fourth magnetizing step is executed to magnetize the second magnetic layer 5 in its magnetizing direction at a lower temperature and a higher magnetic field than those in the third magnetizing step.
