Perfect optical absorption-enhanced magneto-optic Kerr effect microscopy
Dongha Kim, Young-Wan Oh, Jong-Uk Kim +4
Magnetic and spintronic media have offered fundamental scientific subjects and technological applications. Magneto-optic Kerr effect (MOKE) microscopy provides the most accessible…
Temperature dependence of magnetic resonance in ferrimagnetic GdFeCo alloys
Takaya Okuno, Se Kwon Kim, Takahiro Moriyama +10
We provide a macroscopic theory and experimental results for magnetic resonances of antiferromagnetically-coupled ferrimagnets. Our theory, which interpolates the dynamics of antif…
Prediction of topological Hall effect in a driven magnetic domain wall
Kab-Jin Kim, Masahito Mochizuki, Teruo Ono
We investigate the possible emergence of topological Hall effect (THE) in a driven magnetic DW. Numerical simulation based on the Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equatio…
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…
