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…
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…
Very low critical current density for motion of coupled domain walls in synthetic ferrimagnet nanowires
Serban Lepadatu, Henri Saarikoski, Robert Beacham +12
Domain walls in ferromagnetic nanowires are potential building-blocks of future technologies such as racetrack memories, in which data encoded in the domain walls are transported u…
Dynamics of coupled vortices in a pair of ferromagnetic disks
Satoshi Sugimoto, Yasuhiro Fukuma, Shinya Kasai +3
We here experimentally demonstrate that coupled gyration modes can be resonantly excited primarily by the ac current in a pair of ferromagnetic disks with varied separating distanc…
