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 11):
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 a potential difference in accordance with the magnetization direction of the free magnetization layer with respect to a magnetization direction of the fixed magnetization layer occurs in the reading unit by causing a predetermined current to flow through the fixed magnetization layer, the nonmagnetic layer, and the free magnetization layer.
