Ultra-fast GHz-range swept-tuned spectrum analyzer with 20 ns temporal resolution based on a spin-torque nano-oscillator with a uniformly magnetized 'free' layer
Artem Litvinenko, Ahmed Sidi El Valli, Vadym Iurchuk +5
The advantage of an ultra-fast frequency-tunability of spin-torque nano-oscillators (STNOs) that have large (> 100MHz) relaxation frequency of amplitude fluctuations is exploited t…
Control of the Bose-Einstein Condensation of Magnons by the Spin-Hall Effect
Michael Schneider, David Breitbach, Rostyslav O. Serha +13
Previously, it has been shown that rapid cooling of yttrium-iron-garnet (YIG)/platinum (Pt) nano structures, preheated by an electric current sent through the Pt layer, leads to ov…
A tunable magneto-acoustic oscillator with low phase noise
A. Litvinenko, R. Khymyn, V. Tyberkevych +3
A frequency-tunable low phase noise magneto-acoustic resonator is developed on the base of a parallel-plate straight-edge bilayer consisting of a yttrium-iron garnet (YIG) layer gr…
Terahertz frequency spectrum analysis with a nanoscale antiferromagnetic tunnel junction
P. Yu. Artemchuk, O. R. Sulymenko, S. Louis +7
A method to perform spectrum analysis on low power signals between 0.1 and 10 THz is proposed. It utilizes a nanoscale antiferromagnetic tunnel junction (ATJ) that produces an osci…
Spintronic nano-scale harvester of broadband microwave energy
Bin Fang, Mario Carpentieri, Steven Louis +15
The harvesting of ambient radio-frequency (RF) energy is an attractive and clean way to realize the idea of self-powered electronics. Here we present a design for a microwave energ…
THz-Frequency Spin-Hall Auto-Oscillator Based on a Canted Antiferromagnet
O. R. Sulymenko, O. V. Prokopenko, V. S. Tiberkevich +3
We propose a design of a THz-frequency signal generator based on a layered structure consisting of a current-driven platinum (Pt) layer and a layer of an antiferromagnet (AFM) with…
