Abstract

A data reader may be configured at least with a magnetic stack positioned on an air bearing surface (ABS) and contacting a spin depolarizing layer that is a minority spin current carrier. The spin depolarizing layer can have a thickness and spin diffusion length corresponding to a net zero spin polarization at an interface of the magnetic stack and spin depolarizing layer.
