Dimensional crossover in spin Hall oscillators
Andrew Smith, Kemal Sobotkiewich, Amanatullah Khan +9
Auto-oscillations of magnetization driven by direct spin current have been previously observed in multiple quasi-zero-dimensional (0D) ferromagnetic systems such as nanomagnets and…
Immunity of nanoscale magnetic tunnel junctions to ionizing radiation
Eric Arturo Montoya, Jen-Ru Chen, Randy Ngelale +9
Spin transfer torque magnetic random access memory (STT-MRAM) is a promising candidate for next generation memory as it is non-volatile, fast, and has unlimited endurance. Another…
Giant magnetoresistance amplifier for spin-orbit torque nano-oscillators
Jen-Ru Chen, Andrew Smith, Eric A. Montoya +2
Spin-orbit torque nano-oscillators based on bilayers of ferromagnetic (FM) and nonmagnetic (NM) metals are ultra-compact current-controlled microwave signal sources. They serve as…
Injection locking of multiple auto-oscillation modes in a tapered nanowire spin Hall oscillator
Kai Wagner, Andrew Smith, Toni Hache +8
Spin Hall oscillators (SHO) are promising candidates for the generation, detection and amplification of high frequency signals, that are tunable through a wide range of operating f…
Magnetization reversal driven by low dimensional chaos in a nanoscale ferromagnet
Eric Arturo Montoya, Salvatore Perna, Yu-Jin Chen +4
Energy-efficient switching of magnetization is a central problem in nonvolatile magnetic storage and magnetic neuromorphic computing. In the past two decades, several efficient met…
