Claim:
1. A lateral spin valve reader comprising: a detector structure having a surface that forms a portion of a bearing surface; a first shield in contact with the detector structure; a spin injection structure located away from the bearing surface; a second shield in contact with the spine injection structure; a channel layer extending from the detector structure to the spin injection structure; a tunnel barrier layer between at least one of the detector structure and the channel layer or the spin injection structure and the channel layer; and an exterior cladding, disposed around the channel layer, configured to suppress spin-scattering at surfaces of the channel layer, wherein a thickness of the exterior cladding relative to the channel layer is between about 2.5 nanometers and about 20 nanometers, and wherein a thickness of the tunnel barrier layer is less than the thickness of the exterior cladding.
