Correlation between Compensation Temperatures of Magnetization and Angular Momentum in GdFeCo Ferrimagnets
Yuushou Hirata, Duck-Ho Kim, Takaya Okuno +8
Determining the angular momentum compensation temperature of ferrimagnets is an important step towards ferrimagnetic spintronics, but is not generally easy to achieve it experiment…
Distinct domain-wall motion between creep and flow regimes near the angular momentum compensation temperature of ferrimagnet
Yuushou Hirata, Duck-Ho Kim, Takaya Okuno +6
We investigate a magnetic domain-wall (DW) motion in two dynamic regimes, creep and flow regimes, near the angular momentum compensation temperature (T_A) of ferrimagnet. In the fl…
Chirality-induced Antisymmetry in Magnetic Domain-Wall Speed
Dae-Yun Kim, Min-Ho Park, Yong-Keun Park +6
In chiral magnetic materials, numerous intriguing phenomena such as built in chiral magnetic domain walls (DWs) and skyrmions are generated by the Dzyaloshinskii Moriya interaction…
Microscopic Origin of Interfacial Dzyaloshinskii-Moriya Interaction
Sanghoon Kim, Kohei Ueda, Gyungchoon Go +15
Chiral spin textures at the interface between ferromagnetic and heavy nonmagnetic metals, such as Neel-type domain walls and skyrmions, have been studied intensively because of the…
Magnetic Domain-Wall Tilting due to Domain-Wall Speed Asymmetry
Dae-Yun Kim, Min-Ho Park, Yong-Keun Park +8
Chiral magnetic materials provide a number of challenging issues such as the highly efficient domain wall (DW) and skyrmion motions driven by electric current, as of the operation…
Fast domain wall motion induced by antiferromagnetic spin dynamics at the angular momentum compensation temperature of ferrimagnets

Antiferromagnetic spintronics is an emerging research field which aims to utilize antiferromagnets as core elements in spintronic devices. A central motivation toward this directio…
Spin-orbit effective fields in Pt/GdFeCo bilayers
Woo Seung Ham, Sanghoon Kim, Duck-Ho Kim +6
In the increasing interests on spin-orbit torque (SOT) with various magnetic materials, we investigated SOT in rare earth-transition metal ferrimagnetic alloys. The harmonic Hall m…
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…
Magnetic droplet nucleation with homochiral Neel domain wall
Sanghoon Kim, Peong-Hwa Jang, Duck-Ho Kim +5
We investigate the effect of the Dzyaloshinskii Moriya interaction (DMI) on magnetic domain nucleation in a ferromagnetic thin film with perpendicular magnetic anisotropy. We propo…
