Abstract
Roughly described, a magnetic structure includes an electrically conductive path for carrying current flow, a soft magnetic material with high permeability value in magnetic communication with the current flow so that it can be magnetized in either of two directions, and a magnetic device such as a magnetic random access memory cell, having an active layer that is quantum mechanically or magnetostatically coupled to the soft magnetic material. The soft magnetic material acts as an intermediary between the magnetic induction of the current flow and the magnetization of the active layer of the magnetic device to reduce the writing current.
