Angle-dependence and optimal design for magnetic bubblecade with maximum speed
Duck-Ho Kim, Kyoung-Woong Moon, Sang-Cheol Yoo +4
Unidirectional magnetic domain-wall motion is a key concept underlying next-generation application devices. Such motion has been recently demonstrated by applying an alternating ma…
Wide-Range Probing of Dzyaloshinskii-Moriya Interaction
Duck-Ho Kim, Sang-Cheol Yoo, Dae-Yun Kim +2
Dzyaloshinskii-Moriya interaction (DMI) in magnetic objects is of enormous interest, because it generates a built-in chirality of magnetic domain walls (DWs) and topologically-prot…
Universality of Dzyaloshinskii-Moriya interaction effect over domain-wall creep and flow regimes
Duck-Ho Kim, Sang-Cheol Yoo, Dae-Yun Kim +2
Chirality causes diverse phenomena in nature such as the formation of biological molecules, antimatters, non-collinear spin structures, and magnetic skyrmions. The chirality in mag…
Drastic emergence of huge negative spin-transfer torque in atomically thin Co layers
Soong-Geun Je, Sang-Cheol Yoo, Joo-Sung Kim +3
Current-induced domain wall (DW) motion has drawn great attention in the last decades as the key operational principle of emerging magnetic memory devices. As the major driving for…
Magnetic Bubblecade Memory
Kyoung-Woong Moon, Duck-Ho Kim, Sang-Cheol Yoo +6
Unidirectional motion of magnetic domain walls is the key concept underlying next-generation domain-wall-mediated memory and logic devices. Such motion has been achieved either by…
Asymmetric Magnetic Domain-Wall Motion by the Dzyaloshinskii-Moriya Interaction
Soong-Geun Je, Duck-Ho Kim, Sang-Cheol Yoo +3
We demonstrate here that ultrathin ferromagnetic Pt/Co/Pt films with perpendicular magnetic anisotropy exhibit a sizeable Dzyaloshinskii-Moriya interaction (DMI) effect. Such a DMI…
