Magnetoresistive sensor unit with magnetic anisotropic sensor part

摘要

The underside (10) of the sensor part (2) lies opposite the top side (3) of the sensor part. The compensation layer (11) of soft magnetic material is arranged parallel to the underside (10) of the sensor part (2). The dimension (width Bk) of the compensation layer (11) is at least greater than the corresp. dimension (Bm) of the sensor part (2), vertically related to the basic setting direction of the magnetisation (M).
