Abstract
At the interfaces between heavy metals and ferromagnets, a strong spin-orbit coupling(SOC) plays an important role in various magnetic phenomena such as perpendicularmagnetic anisotropy (PMA), magnetostriction effects, anomalous Hall effects, anisotropicmagnetoresistances, and magnetic damping processes. [1,2] Recently, the interfacialDzyaloshinskii-Moriya interaction (DMI), a brand new interface effect originated by a strongSOC, has been of great interest because of its interesting physical roles in the chiral spinconfiguration in PMA system such as Neel-type domain wall and a nanomagnetic skyrmion.Both spin structures are very promising candidates for future information-processing deviceswith high efficiency and ultrahigh density data storage capabilities.
