Excitation of the Gyrotropic Mode in a Magnetic Vortex by Time-Varying Strain
Vadym Iurchuk, Jürgen Lindner, Jürgen Fassbender +1
We demonstrate excitation of the gyrotropic mode in a magnetostrictive vortex by time-varying strain. The vortex dynamics is driven by a time-varying voltage applied to the piezoel…
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…
Stress-induced modification of gyration dynamics in stacked double-vortex structures studied by micromagnetic simulations
Vadym Iurchuk, Attila Kákay, Alina M. Deac
In this paper, using micromagnetic simulations, we investigate the stress-induced frequency tunability of double-vortex nano-oscillators comprising magnetostrictive and non-magneto…
Experimental demonstration of a rapid sweep-tuned spectrum analyzer with temporal resolution based on a spin-torque nano-oscillator
A. Litvinenko, V. Iurchuk, P. Sethi +8
It is demonstrated experimentally that a spin-torque nano-oscillator (STNO) rapidly sweep-tuned by a bias voltage can be used for time-resolved spectrum analysis of frequency-manip…
