Abstract: A data reader may have an resonant tunnel structure disposed between first and second magnetic structures. The resonant tunnel structure can be configured with a spacer layer disposed between first and second barrier layers. The first barrier layer can have a first thickness that is smaller than a second thickness of the second barrier layers with the thicknesses each measured along a common plane to provide resonant tunneling for the data reader.

Abstract: A lateral spin valve reader includes a detector located proximate to a bearing surface of the reader, a spin injector located away from the bearing surface, and a channel layer that substantially extends from the detector to the spin injector. The channel layer and the detector are substantially in a same plane.

Abstract: A lateral spin valve reader includes a detector located proximate to a bearing surface of the reader, and a spin injector located away from the bearing surface. The lateral spin valve reader also includes a channel that extends from the detector to the spin injector. The channel includes a two-dimensional semiconducting layer that extends from the detector to the spin injector.

Abstract: A lateral spin valve reader and fabrication method thereof. The method includes forming an injector, a detector and a common channel layer that extends from the injector to the detector. The method also includes forming a first channel layer between the common channel layer and at least one of the injector or the detector with the first channel layer in contact with the common channel layer, thereby providing an interface between the first channel layer and the common channel layer.

Abstract: A data reader may be configured with at least a detector stack positioned on an air bearing surface and consisting of a spin accumulation channel continuously extending from the air bearing surface to an injector stack. The injector stack can have at least one cladding layer contacting the spin accumulation channel. The at least one cladding layer may have a length as measured perpendicular to the ABS that filters minority spins from the detector stack.

Abstract: Implementations described and claimed herein include a method for manufacturing monolithically-integrated on-slider hybridized electronics for magnetic read/write. The method includes forming a slider body, excising a void in a surface of the slider body, monolithically integrating an electronic block into the void of the slider body, polishing the surface of the slider body, and depositing functional layers on the surface of the slider body. By integrating electronics in close proximity to transducers, operational performance and functionality may be gained.

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.
