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…
Impact of intra-grain spin wave reflections on nano-contact spin torque oscillators
Anders J. Eklund, Mykola Dvornik, Fatjon Qejvanaj +4
We investigate the origin of the experimentally observed varying current-frequency nonlinearity of the propagating spin wave mode in nano-contact spin torque oscillators. Nominally…
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…
Magnetic Droplet Soliton Nucleation in Oblique Fields
Morteza Mohseni, M. Hamdi, H. F. Yazdi +5
We study the auto-oscillating magnetodynamics in orthogonal spin torque nano-oscillators (STNOs) as a function of the out-of-plane (OOP) magnetic field angle. In perpendicular fiel…
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…
