发明名称 MAGNETORESISTIVE DEVICE, MAGNETORESISTIVE RANDOM ACCESS MEMORY AND MAGNETIC RECORDING METHOD
摘要 A magnetoresistive device includes a magnetic free layer having first and second surfaces, the magnetic free layer being comprised of a ferromagnetic material having a perpendicular magnetic anisotropy, a spin current generation layer contacting the first surface of the magnetic free layer, a tunnel barrier layer having one surface contacting the second surface of the magnetic free layer, a reference layer contacting another surface of the tunnel barrier layer, and a leakage field generation layer including first and second leakage field generation layers each of which is comprised of a ferromagnetic material and generates a leakage field, an in-plane component of the leakage field at an part of the magnetic free layer is formed generating a domain wall having an in-plane magnetization component in the magnetic free layer.
