Spin-transfer torques for domain walls in antiferromagnetically coupled ferrimagnets
Takaya Okuno, Duck-Ho Kim, Se-Hyeok Oh +13
Antiferromagnetic materials are outstanding candidates for next generation spintronic applications, because their ultrafast spin dynamics makes it possible to realize several order…
Enhanced perpendicular magnetocrystalline anisotropy energy in an artificial magnetic material with bulk spin-momentum coupling
Abdul-Muizz Pradipto, Kay Yakushiji, Woo Seung Ham +8
We systematically investigate the perpendicular magnetocrystalline anisotropy (MCA) in CoPt/Pd-based multilayers. Our magnetic measurement data shows that the asymmetric Co/Pd/P…
Enhanced spin-orbit torque via interface engineering in Pt/CoFeB/MgO heterostructures
Hae-Yeon Lee, Sanghoon Kim, June-Young Park +9
Spin-orbit torque facilitates efficient magnetization switching via an in-plane current in perpendicularly magnetized heavy metal/ferromagnet heterostructures. The efficiency of sp…
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…
Fast domain wall motion induced by antiferromagnetic spin dynamics at the angular momentum compensation temperature of ferrimagnets
Kab-Jin Kim, Se Kwon Kim, Takayuki Tono +11
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…
