Coexisting and interacting spin torque driven free and reference layer magnetic droplet solitons
Sheng Jiang, Sunjae Chung, Martina Ahlberg +6
Magnetic droplets are nanoscale, non-topological, magnetodynamical solitons that can be nucleated in spin torque nano-oscillators (STNOs) or spin Hall nano-oscillators (SHNOs). All…
Freezing and thawing magnetic droplet solitons
Martina Ahlberg, Sunjae Chung, Sheng Jiang +10
Magnetic droplets are non-topological magnetodynamical solitons displaying a wide range of complex dynamic phenomena with potential for microwave signal generation. Bubbles, on the…
Compositional effect on auto-oscillation behavior of Ni100-xFex/Pt spin Hall nano-oscillators
M. Haidar, H. Mazraati, P. Dürrenfeld +3
We demonstrate the compositional effect on the magnetodynamic and auto-oscillations properties of Ni100-xFex/Pt (x= 10 to 40) nanoconstriction based spin Hall nano-oscillators. Usi…
Two-dimensional mutual synchronization in spin Hall nano-oscillator arrays
Mohammad Zahedinejad, Ahmad A. Awad, Shreyas Muralidhar +5
Spin Hall nano-oscillators (SHNOs) utilize pure spin currents to drive local regions of magnetic films and nanostructures into auto-oscillating precession. If such regions are plac…
Mutual synchronization of constriction-based spin Hall nano-oscillators in weak in-plane fields
Hamid Mazraati, Shreyas Muralidhar, Seyyed Ruhollah Etesami +6
We study mutual synchronization in double nanoconstriction-based spin Hall nano-oscillators (SHNOs) under weak in-plane fields ( = 30-40 mT) and also investigate…
Mapping out the spin-wave modes of constriction-based spin Hall nano-oscillators in weak in-plane fields
Hamid Mazraati, Seyyed Ruhollah Etesami, Seyed Amir Hossein Banuazizi +5
We experimentally study the auto-oscillating spin-wave modes in NiFe/W constriction-based spin Hall nano-oscillators as a function of bias current, in-plane applied field stren…
CMOS compatible W/CoFeB/MgO spin Hall nano-oscillators with wide frequency tunability
M. Zahedinejad, H. Mazraati, H. Fulara +4
We demonstrate low-operational-current W/CoFeB/MgO spin Hall nano-oscillators (SHNOs) on highly resistive silicon (HiR-Si) substrates. Thanks to a record high…
Direct observation of magnetic droplet solitons in all-perpendicular spin torque nano-oscillators
Sunjae Chung, Q. Tuan Le, Martina Ahlberg +11
Magnetic droplets are non-topological dynamical solitons that can be nucleated and sustained in nano-contact based spin torque nano-oscillators (NC-STNOs) with perpendicular anisot…
