  • Magnetoresistive thin-film magnetic element and method for making the same
    Patent number: 6656604
    Abstract: A magnetoresistive thin-film magnetic element including a composite comprising an antiferromagnetic layer, a pinned magnetic layer, a nonmagnetic conductive layer, a free magnetic layer; hard bias layers for orienting the magnetic vectors of the free magnetic layer in a direction substantially orthogonal to the magnetization vector of the pinned magnetic layer; and a conductive layer for supplying a sense current is provided. The hard bias layers are provided at the two sides of the free magnetic layer. The hard bias layers and the free magnetic layers are in contact with each other at least partly. Bias underlayers are provided at the bottom of the hard bias layers.
    Type: Grant
