Title:
HIGH-SPEED AND HIGH-ENERGY-EFFICIENCY MAGNETIC TUNNEL JUNCTION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2024/010347
Kind Code:
A1
Abstract:
The present technology relates to a high-speed and high-energy-efficiency magnetic tunnel junction element. The high-speed and high-energy-efficiency magnetic tunnel junction element of the present technology comprises: a main pinned layer having a magnetization direction determined in a first direction; an auxiliary pinned layer distinguished from the main pinned layer by an insulator (insulating material) and having a magnetization direction determined in a second direction crossing the first direction; an oxide barrier layer stacked on the main pinned layer and the auxiliary pinned layer; and a free layer stacked on the oxide barrier layer and having a stable magnetization state parallel and antiparallel to the magnetization direction of the main pinned layer. The present technology provides a novel three-terminal magnetic tunnel junction element having an auxiliary ferromagnet perpendicular to the magnetization of the free layer.
