Abstract
A lateral spin valve reader includes a channel layer having a first end that is proximate to a bearing surface and a second end that is away from the bearing surface. The lateral spin valve reader also includes a detector structure disposed over an upper surface of a first portion of the channel layer that is proximate to the first end of the channel layer. A spin injection structure disposed below a lower surface of a second portion of the channel layer is proximate to the second end of the channel layer. An area of overlap between the spin injection structure and the second portion of the channel layer is substantially larger than an area of overlap between the detector structure and the first portion of the channel layer.
