    摘要: Provided are magnetoresistive elements, memory devices including the same, and an operation methods thereof. A magnetoresistive element may include a free layer, and the free layer may include a plurality of regions (layers) having different properties. The free layer may include a plurality of regions (layers) having different Curie temperatures. The Curie temperature of the free layer may change regionally or gradually away from the pinned layer. The free layer may include a first region having ferromagnetic characteristics at a first temperature and a second region having paramagnetic characteristics at the first temperature. The first region and the second region both may have ferromagnetic characteristics at a second temperature lower than the first temperature. The effective thickness of the free layer may change with temperature.

    摘要: Magnetic memory devices include a magnetoresistive cell including a free layer having a variable magnetization direction and a pinned layer having a fixed magnetization direction, a bit line on the magnetoresistive cell and including a spin Hall effect material layer exhibiting a spin Hall effect and contacting the free layer; and a lower electrode under the magnetoresistive cell. A voltage is applied between the bit line and the lower electrode so that current passes through the magnetoresistive cell.

    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.
