Temperature dependence of charge-to-spin conversion in rhombohedral (110) bismuth thin film
K. Tatsuoka, N. Fukumoto, S. Sakamoto +7
The amplitude of charge-to-spin conversion, namely the spin Hall effect (SHE), in bismuth (Bi) strongly depends on its crystal orientation. The conversion efficiency at room temper…
Reinforcement-Learning-Designed Field-Free Sub-Nanosecond Spin-Orbit-Torque Switching
Yuta Igarashi, Junji Fujimoto
We demonstrate deterministic, field-free magnetization reversal of a single-domain nanomagnet within 300 ps under a current density of by coupling…
Magnetic Moment vs Angular Momentum: Spin Hall Response in Bismuth
Junji Fujimoto, Yuki Izaki, Yuki Fuseya
Spin currents can carry either spin angular momentum or its associated magnetic moment, which are no longer strictly proportional in multiband systems. Using a multiband $k \cdot p…
Intrinsic spin Nernst effect in topological Dirac and magnetic Weyl semimetals
Taiki Matsushita, Akihiro Ozawa, Yasufumi Araki +2
We investigate the intrinsic spin Nernst effect (SNE), a transverse spin current induced by temperature gradients, in topological Dirac semimetals (TDSMs) and magnetic Weyl semimet…
Microscopic theory of spin Nernst effect
Junji Fujimoto, Taiki Matsushita, Masao Ogata
We present the microscopic theory of the spin Nernst effect, which is a transverse spin current directly induced by a temperature gradient, employing the linear response theory wit…
