Snell's Law for Spin Waves
Johannes Stigloher, Martin Decker, Helmut S. Körner +9
We report the experimental observation of Snell's law for magneto-static spin waves in thin ferromagnetic Permalloy films by imaging incident, refracted and reflected waves. We use…
Antiferromagnetic spintronics
V. Baltz, A. Manchon, M. Tsoi +3
Antiferromagnetic materials could represent the future of spintronic applications thanks to the numerous interesting features they combine: they are robust against perturbation due…
Giant modulation of the magnetic domain size induced by an electric field
Fuyuki Ando, Haruka Kakizakai, Tomohiro Koyama +7
The electric field (EF) effect on the magnetic domain structure of a Pt/Co system was studied, where an EF was applied to the top surface of the Co layer. The width of the maze dom…
Current-induced asymmetric magnetoresistance due to energy transfer via quantum spin-flip process
K. J. Kim, T. Moriyama, T. Koyama +6
Current-induced magnetization excitation is a core phenomenon for next-generation magnetic nanodevices, and has been attributed to the spin-transfer torque (STT) that originates fr…
Switching local magnetization by electric-field-induced domain wall motion
H. Kakizakai, F. Ando, T. Koyama +7
Electric field effect on magnetism is an appealing technique for manipulating the magnetization at a low cost of energy. Here, we show that the local magnetization of the ultra-thi…
Anomalous behavior of 1/f noise in graphene near the charge neutrality point
Shunpei Takeshita, Sadashige Matsuo, Takahiro Tanaka +6
We investigate the noise in single layer graphene devices from equilibrium to far from equilibrium and found that the 1/f noise shows an anomalous dependence on the source-drain bi…
