CPP magnetoresistive device and method for making same |
摘要 |
A magnetoresistive device includes a metal layer, formed over a substrate, in which a groove is formed. A magnetoresistive element is formed in the groove, forming two magnetoresistive element portions that are separated by a conductive element. A sense current applied to the metal layer flows through the two magnetoresistive element portions with a predominant current-perpendicular-to-plane component. A method includes techniques that are less complex and less expensive than submicron photolithography to form the above described magnetoresistive device with submicron geometries. A system includes a read/write head that incorporates a magnetoresistive element formed in a groove of a metal layer.
