摘要： A magnetic structure for use in a magnetic recording head, the structure having improved resistance to stray field writing. The magnetic structure can be for example a magnetic shield or a return pole of a perpendicular write element. The structure includes a main body portion which may have a generally rectangular configuration, and first and second wing portions extending laterally from the sides of the body at or near the ABS. The wing portions have a depth measured perpendicular to the ABS that is significantly less than the depth of the body portion (preferably less than 25 percent of the body portion). The wing portions may also have notches formed in their ABS edges. The wings conduct flux from the ABS edge of the body portion and create a flux choking effect for magnetic flux flowing into the wings.

摘要： A magnetoresistive sensor having employing a Mn containing Huesler alloy for improved magnetoresistive performance in a structure that minimizes corrosion and Mn migration. The sensor can be constructed with a pinned layer structure that includes a lamination of layers of Co2MnX and CoFe, where X is Al, Ge or Si. The Co2MnX can be sandwiched between the layers of CoFe to prevent Mn migration into the spacer/barrier layer. The free layer can also be constructed as a lamination of Co2MnX and CoFe layers, and may also be constructed so that the Co2MnX layer is sandwiched between CoFe layers to prevent Mn migration.

摘要： A magnetoresistive sensor having a scissor free layer design and no pinned layer. The sensor includes first and second free layers that have magnetizations that are oriented at 90 degrees to one another and has a third magnetic layer with a magnetization that is antiparallel coupled with one of the free layers. The antiparallel coupling of the third magnetic layer with one of the free layers, allows the sensor to be used in a tunnel valve design, having an electrically insulating barrier layer between the free layers. The tunnel valve design reduces spin torque noise in the sensor, and the presence of the third magnetic layer allows the free layers to remain bias at 90 degrees to one another in spite of interfacial coupling through the very thin barrier layer.
