Title:
交換結合側面遮蔽構造を備えた面垂直電流（ＣＰＰ）磁気抵抗（ＭＲ）センサ
Document Type and Number:
Japanese Patent JP5816673
Kind Code:
B2
Abstract:
A current-perpendicular-to-the-plane magnetoresistive sensor has an exchange-coupled side shield structure on each of two side regions of the sensor and an exchange-coupled top shield structure on the sensor and the two exchange-coupled side shield structures. Each exchange-coupled structure comprises an antiferromagnetic layer and a shield of soft magnetically permeable material exchange-coupled with the antiferromagnetic layer. Each side shield and the top shield has its magnetization oriented generally parallel to the sensor front edge and generally parallel to the plane of the sensor's free ferromagnetic layer. The shields in each exchange-coupled side shield structure and the exchange-coupled top shield structure may be an antiparallel coupled structure of two magnetically permeable films separated by a nonmagnetic coupling film.
