Abstract

PURPOSE: To adjust a bias DC magnetic field applied to a magnetic resistance effect element film to the best value, by magnetizing a hard magnetic thin film, arranged in the width direction of the magnetic resistance effect element film, at more than the curie temperature of a substrate and protecting substrate.
CONSTITUTION: Hard magnetic thin film 3 arranged in the width direction of magnetic resistance effect element film 5 is magnetized at more than the curie temperature of substrate 1 and protecting substrate 9 made of soft magnetic materials. In this case, it is preferable that changes of magnetic characteristics and surface states of hard magnetic thin film 3 and magnetic resistance effect film 5 due to the high temperature in the magnetization are prevented by using Xi-Zn or Mn-Zn ferrite of about ≤200°C curie temperature for substrate 1 and protecting substrate 9. Thus, a bias magnetic field applied to film 5 can be adjusted to the best value by eliminating magnetic charges residing at y-directional flank parts 1a and 9a of substrate 1 and protecting substrate 9 during the magnetization of thin film 3.
