Nonreciprocal spin-wave dispersion in magnetic bilayers
C. Heins, V. Iurchuk, O. Gladii +5
Nonreciprocal spin-wave propagation in bilayer ferromagnetic systems has attracted significant attention due to its potential to precisely quantify material parameters as well as f…
Strain-induced frequency pulling in CoFeB/Cu/Py double-vortex oscillators
Vadym Iurchuk, Jürgen Lindner, Jürgen Fassbender +1
We demonstrate piezostrain-induced frequency pulling in stacked double-vortex structures, magnetostatically coupled through the nonmagnetic spacer. We study the effect of the Cu sp…
Anatomy of localized edge modes in laterally coupled waveguides
Vadym Iurchuk, Sven Stienen, Jürgen Lindner +1
We present a systematic micromagnetic study of standing spin-wave modes in infinitely long Permalloy strips with rectangular cross-section. Using a finite-element dynamic-matrix me…
Piezostrain -- a local handle to control gyrotropic dynamics in magnetic vortices
Vadym Iurchuk, Serhii Sorokin, Jürgen Lindner +2
We present a study of the piezostrain-tunable gyrotropic dynamics in CoFeB vortex microstructures fabricated on a 0.7PMN-0.3PT single crystalline substrate. Us…
Tailoring crosstalk between localized 1D spin-wave nanochannels using focused ion beams
Vadym Iurchuk, Javier Pablo-Navarro, Tobias Hula +8
1D spin-wave conduits are envisioned as nanoscale components of magnonics-based logic and computing schemes for future generation electronics. `A-la-carte methods of versatile cont…
Effects of the rf current and bias field direction on the transition from linear to non-linear gyrotropic dynamics in magnetic vortex structures
Lakshmi Ramasubramanian, Vadym Iurchuk, Serhii Sorokin +2
We present a frequency-domain study of the dynamic behavior of a magnetic vortex core within a single Permalloy disk by means of electrical detection and micromagnetic simulations.…
Size-dependent enhancement of passive microwave rectification in magnetic tunnel junctions with perpendicular magnetic anisotropy
A. Sidi El Valli, V. Iurchuk, G. Lezier +11
Spintronic rf detectors were demonstrated, recently, for energy harvesting and wireless communication at low input power. Here we report on the optimization of the rectified output…
Resonant state selection in synthetic ferrimagnets
B. C. Koop, Yu. I. Dzhezherya, K. Demishev +3
Resonant activation of a synthetic antiferromagnet (SAF) is known to result in a dynamic running state, where the SAF's symmetric spin-flop pair continuously rotates between the tw…
