Abstract:
A memory element ( 10 ) includes a free magnetization layer ( 12 ) in a film form, a nonmagnetic layer ( 13 ), and a fixed magnetization layer ( 14 ), the nonmagnetic layer ( 13 ) and the fixed magnetization layer ( 14 ) being stacked on the free magnetization layer ( 12 ). The free magnetization layer ( 12 ) stores a single bit of data “0” or “1” according to a magnetization direction and rewrites the data by reversing the magnetization direction. An antiferromagnet that exhibits the anomalous Hall effect and has a reversible magnetization direction is used for the free magnetization layer ( 12 ). The reversal of the magnetization direction of the free magnetization layer ( 12 ) is performed using the fixed magnetization layer ( 14 ) by the spin-transfer torque technique. To read data, a reading current (If) is caused to flow in one direction, and a Hall voltage generated in the free magnetization layer ( 12 ) by the anomalous Hall effect is extracted from the free magnetization layer ( 12 ). The polarity of the Hall voltage is reversed in accordance with the magnetization direction of the free magnetization layer ( 12 ).

Claim (Index 10):
The memory element according to  claim 1 , comprising:\n a nonmagnetic layer stacked on a film surface of the free magnetization layer; and a fixed magnetization layer having a fixed magnetization direction, wherein the nonmagnetic layer is disposed between the free magnetization layer and the fixed magnetization layer, and an electric current in accordance with the magnetization direction of the free magnetization layer with respect to a magnetization direction of the fixed magnetization layer is caused to flow through the reading unit by application of a predetermined voltage to the fixed magnetization layer, the nonmagnetic layer, and the free magnetization layer.
