To provide a method for fabricating a magnetic detection element in which magnetizing direction of a fixed magnetic layer can be controlled surely even if a hard magnetic layer is magnetized after magnetizing direction of the fixed magnetic layer is fixed in a self-fixing magnetic detection element.
The method for fabricating a magnetic detection element comprises a step for imparting the hard magnetic layer 28 and the fixed magnetic layer 23 with a magnetic field greater than the coercive force of the hard magnetic layer 28 in the direction of a specified angle with respect to a first direction and arranging the magnetizing direction of the hard magnetic layer 28 and the fixed magnetic layer 23 to the angular direction, a step for reducing the magnetic field gradually below the spin flop magnetic field of the fixed magnetic layer 23 and making the magnetizing direction of two magnetic layers 23a and 23c constituting the fixed magnetic layer 23 antiparallel, and a step for removing the magnetic field and rotating the magnetizing direction of both magnetic layers 23a and 23c to the direction coaxial with a second direction intersecting the first direction.
