A spin accumulation magnetic sensor having improved signal strength and efficiency. The spin accumulation magnetic sensor has a detector structure and a spin injection structure and has a non-magnetic, electrically conductive layer extending between the spin injection structure and the detector structure. The detector structure has first and second free layers arranged such that the non-magnetic, electrically conductive layer extends between them and so that they are magnetically anti-parallel coupled with one another. The spin injection structure can also include first and second magnetic layers with the electrically conductive layer extending between them and with the first magnetic layer being pinned and the second magnetic layer being anti-parallel coupled with the first magnetic layer. |
