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…
Frequency Stability of Spin-Hall Nano-Oscillators with Realistic Grain Structure
Corrado Carlo Maria Capriata, Sheng Jiang, Mykola Dvornik +2
Nano-constriction spin-Hall nano-oscillators (NC-SHNOs) are one of the most promising alternatives among the microwave spintronics devices. They can provide highly coherent and wid…
Observation of Magnetic Droplets in Magnetic Tunnel Junctions
Kewen Shi, Wenlong Cai, Sheng Jiang +10
Magnetic droplets, a class of highly non-linear magnetodynamical solitons, can be nucleated and stabilized in nanocontact spin-torque nano-oscillators where they greatly increase t…
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…
Tuning spin torque nano-oscillator nonlinearity using He+ irradiation
Sheng Jiang, Roman Khymyn, Sunjae Chung +6
We use He irradiation to tune the nonlinearity, , of all-perpendicular spin-torque nano-oscillators (STNOs) using the He fluence-dependent perpendicular magnet…
Tuning the magnetodynamic properties of all-perpendicular spin valves using He+ irradiation
S. Jiang, S. Chung, L. Herrera Diez +4
Using He+ ion irradiation, we demonstrate how the magnetodynamic properties of both ferromagnetic layers in all-perpendicular [Co/Pd]/Cu/[Co/Ni] spin valves can be tuned by varying…
