Negative correlation between the linear and the nonlinear conductance in magnetic tunnel junctions
Shuichi Iwakiri, Satoshi Sugimoto, Yasuhiro Niimi +4
The current-voltage () characteristics beyond the linear response regime of magnetic tunnel junction (MTJ) is systematically investigated. We find a clear negative correlation…
Superdiffusion of Aerosols Emitted After Sneezing -- Nonequilibrium Statistical Mechanics Approach
Satoshi Sugimoto, Ken Umeno
We study a stochastic behavior of aerosols by the non-equilibrium statistical mechanics approach using the analytical approach of the Langevin equation. We firstly show that superd…
Modeling characterisation of a bipolar pulsed discharge
Zoltan Donko, Lenka Zajickova, Satoshi Sugimoto +2
We apply particle based kinetic simulations to explore the characteristics of a low-pressure gas discharge driven by high-voltage ( kV) pulses with alternating polarity, wit…
Generation of Multipeak Spectrum of Spin Torque Oscillator in Non-linear Regime
Shuichi Iwakiri, Satoshi Sugimoto, Yasuhiro Niimi +4
We investigate the spectral characteristics of spin torque oscillator (STO) excited by the spin Hall-induced spin current. We observe that the modest spin current injection trigger…
Multiple modes of a single spin torque oscillator under the non-linear region
Satoshi Sugimoto, Shuichi Iwakiri, Yusuke Kozuka +4
A numerical investigation is conducted for a single spin-torque oscillator under the non-linear region. A large angle precession triggers the generation of multiple modes without a…
Helical magnetic structure and the anomalous and topological Hall effects in epitaxial B20 FeCoGe films
Charles S. Spencer, Jacob Gayles, Nicholas A. Porter +12
Epitaxial films of the B20-structure alloy FeCoGe were grown by molecular beam epitaxy on Si (111) substrates. The magnetization varied smoothly from the bulk-like valu…
