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.

Abstract: An apparatus can be generally directed to a magnetic stack having a magnetically free layer positioned on an air bearing surface (ABS). The magnetically free layer can be biased to a predetermined magnetization in various embodiments by a biasing structure that is coupled with the magnetically free layer and positioned distal the ABS.

Abstract: A magnetic element may be configured with at least a magnetic stack having first and second magnetically free layers that each has a predetermined stripe height from an air bearing surface (ABS). The first and second magnetically free layers can respectively be configured with first and second uniaxial anisotropies that are crossed in relation to the ABS and angled in response to the predetermined stripe height.

Abstract: A data reader may be configured at least with a magnetic stack that has a first magnetic layer separated from a second magnetic layer by a non-magnetic spacer layer. The first magnetic layer may have an areal extent on an air bearing surface (ABS) that differs from the second magnetic layer while the second magnetic layer can be configured with a first plurality of linear sidewalls that are each angled with respect to a second plurality of linear sidewalls of the first magnetic layer.
