The magnetic flux control layer includes a first layer including a first metal and contacting one of the main magnetic pole and the writing shield, a second control layer, and a third layer including a second metal and contacting the other one of the main magnetic pole and the writing shield. The second control layer includes a magnetic metal and contacts the first layer and the third layer. | 2019-06-20 |
20190189150 | EXCHANGE-COUPLED FILM, MAGNETORESISTIVE ELEMENT INCLUDING THE SAME, AND MAGNETIC SENSING DEVICE - An exchange-coupled film according to the present invention includes an antiferromagnetic layer, pinned magnetic layer, and free magnetic layer which are stacked. The antiferromagnetic layer is composed of a Pt—Cr sublayer and an X-Mn sublayer (where X is Pt or Ir). The X-Mn sublayer is in contact with the pinned magnetic layer. The Pt—Cr sublayer has a composition represented by the formula Pt | 2019-06-20 |
