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 12):
A memory element comprising:\n a free magnetization layer having a reversible magnetization direction; a nonmagnetic layer stacked on a film surface of the free magnetization layer; and a fixed magnetization layer stacked such that the nonmagnetic layer is disposed between the fixed magnetization layer and the free magnetization layer, the fixed magnetization layer being configured to reverse a magnetization direction of the free magnetization layer depending on data to be written, or to extract an electric signal in accordance with the magnetization direction of the free magnetization layer in data reading, wherein at least one of the free magnetization layer and the fixed magnetization layer comprises an antiferromagnet.
