ABSTRACT:
A double tunnel junction TMR magnetoresistive sensor having first and second magnetic free layers separated by a self pinned magnetic layer. The self pinned magnetic layer is separated from the first and second free layers by thin barrier layers. The pinned layer magnetization is pinned without the need for exchange pinning with an adjacent layer of antiferromagnetic layer.
