Abstract
A transducer according to one embodiment comprises a first ferromagnetic layer; a second ferromagnetic layer; and an electrically conductive layer positioned between the ferromagnetic layers; wherein a length of the first ferromagnetic layer in a first direction parallel to a plane of deposition thereof is greater than a length of the electrically conductive layer in the first direction such that a first end of the first ferromagnetic layer extends beyond an end of the electrically conductive layer in the first direction, wherein an electrical current enters or exits the end of the first ferromagnetic layer that extends beyond the end of the electrically conductive layer in the first direction. Additional transducer structures, and systems implementing such transducers, are also disclosed.
