Choking non-local magnetic damping in exchange biased ferromagnets
Takahiro Moriyama, Kent Oda, Teruo Ono
We investigated the temperature dependence of the magnetic damping in the exchange biased Pt/ Fe50Mn50 /Fe20Ni80 /SiOx multilayers. In samples having a strong exchange bias, we obs…
An alternative to the topological interpretation of the transverse resistivity anomalies in SrRuO3
Daisuke Kan, Takahiro Moriyama, Kento Kobayashi +1
We clarify the physical origin of anomalies in transverse resistivity often observed in exotic materials, such as SrRuO3, in which the Berry curvature is manifested in the transpor…
Zener Tunneling Breakdown in Phase-Change Materials Revealed by Intense Terahertz Pulses
Yasuyuki Sanari, Takehiro Tachizaki, Yuta Saito +8
We have systematically investigated the spatial and temporal dynamics of crystallization that occurs in the phase-change material Ge2Sb2Te5 upon irradiation with an intense THz pul…
Quantitative agreement of Dzyaloshinskii-Moriya interactions for domain-wall motion and spin-wave propagation
Dae-Yun Kim, Nam-Hui Kim, Yong-Keun Park +10
The magnetic exchange interaction is the one of the key factors governing the basic characteristics of magnetic systems. Unlike the symmetric nature of the Heisenberg exchange inte…
Spin Seebeck imaging of spin-torque switching in antiferromagnetic Pt/NiO heterostructures
Isaiah Gray, Takahiro Moriyama, Nikhil Sivadas +10
As electrical control of Néel order opens the door to reliable antiferromagnetic spintronic devices, understanding the microscopic mechanisms of antiferromagnetic switching is cruc…
Vanishing skyrmion Hall effect at the angular momentum compensation temperature of a ferrimagnet
Yuushou Hirata, Duck-Ho Kim, Se Kwon Kim +14
Charged particles exhibit the Hall effect in the presence of magnetic fields. Analogously, ferromagnetic skyrmions with non-zero topological charges and finite fictitious magnetic…
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…
Near- and Mid-IR Gas-Phase Absorption Spectra of H2@C60+-He
Dmitry V. Strelnikov, Juraj Jašík, Dieter Gerlich +4
Near- and mid-IR absorption spectra of endohedral H2@C60+ have been measured using He-tagging. The samples have been prepared using a 'molecular surgery' synthetic approach and wer…
Low magnetic damping of ferrimagnetic GdFeCo alloys
Duck-Ho Kim, Takaya Okuno, Se Kwon Kim +12
We investigate the Gilbert damping parameter for rare earth (RE)-transition metal (TM) ferrimagnets over a wide temperature range. Extracted from the field-driven magnetic domain-w…
Learning on Hypergraphs with Sparsity
Canh Hao Nguyen, Hiroshi Mamitsuka
Hypergraph is a general way of representing high-order relations on a set of objects. It is a generalization of graph, in which only pairwise relations can be represented. It finds…
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…
Room Temperature Electrically Detected Nuclear Spin Coherence of NV Centers in Diamond
Hiroki Morishita, Satoshi Kobayashi, Masanori Fujiwara +4
We demonstrate electrical detection of the N nuclear spin coherence of NV centers at room temperature. Nuclear spins are candidates for quantum memories in quantum-informati…
Optimization temperature sensitivity using the optically detected magnetic resonance spectrum of a nitrogen-vacancy center ensemble
Kan Hayashi, Yuichiro Matsuzaki, Takashi Taniguchi +8
Temperature sensing with nitrogen vacancy (NV) centers using quantum techniques is very promising and further development is expected. Recently, the optically detected magnetic res…
Fundamental physics activities with pulsed neutron at J-PARC(BL05)
Kenji Mishima, Shogo Awano, Yasuhiro Fuwa +37
"Neutron Optics and Physics (NOP/ BL05)" at MLF in J-PARC is a beamline for studies of fundamental physics. The beamline is divided into three branches so that different experiment…
Correlation between Magnetic Properties and Depinning Field in Field-Driven Domain Wall Dynamics in GdFeCo Ferrimagnets
Tomoe Nishimura, Duck-Ho Kim, Yuushou Hirata +7
The influence of temperature on the magnetic-field-driven domain wall (DW) motion is investigated in GdFeCo ferrimagnets with perpendicular magnetic anisotropy (PMA). We find that…
