【発明の名称】磁気抵抗型センサ素子、とりわけ角度センサ素子
Document Type and Number:
Japanese Patent JP2002525610
Kind Code:
A
Abstract:
A magnetoresistive sensor element, in particular an angle sensor element, has a first, magnetic layer (3) whose direction of magnetization represents a reference direction, a second, nonmagnetic layer (2) formed on the first layer (3), a third magnetic layer (1), formed on the second layer (2), whose direction of magnetization can be varied by an external magnetic field, and an additional layer consisting of a current conductor (5) for selective orientation of the direction of magnetization of the first layer (3). A current flow direction of an electric current that passes through the current conductor (5) can be switched to change the magnetization direction of the first magnetic layer (3) to create different reference directions. An insulation layer (4) for galvanic separation of the first magnetic layer (3) from the additional layer (5) is also provided between them.
