Abstract
A lateral spin valve reader that includes a detector structure located proximate to a bearing surface and a spin injection structure located away from the bearing surface. The lateral spin valve reader also includes a channel layer extending from the detector structure to the spin injection structure. An exterior cladding, disposed around the channel layer, suppresses spin-scattering at surfaces of the channel layer.
