Magnetoresistive elements and memory devices including the same |
摘要 |
Magnetoresistive elements, and memory devices including the same, include a free layer having a changeable magnetization direction, a pinned layer facing the free layer and having a fixed magnetization direction, and an auxiliary element on a surface of the pinned layer. The auxiliary element has a width smaller than a width of the pinned layer, and a magnetization direction fixed to a direction the same as a direction of the fixed magnetization direction of the pinned layer. |

1. A magnetoresistive element, comprising:
a free layer having a changeable magnetization direction; a pinned layer facing the free layer and having a fixed magnetization direction; and an auxiliary element on a surface of the pinned layer, the auxiliary element directly contacting the pinned layer, wherein the auxiliary element has a width smaller than a width of the pinned layer and a magnetization direction fixed to a direction the same as a direction of the fixed magnetization direction of the pinned layer. |
