Spatially resolved quantum magnetometry and stray-field reconstruction of permalloy microdisks using boron-vacancy centers in hexagonal boron nitride
Peiting Wen, Shuyu Wen, Jiang Qu +13
Transferable hexagonal boron nitride (hBN) hosting negatively charged boron-vacancy (VB) spin defects offers a versatile platform for integrated quantum magnetometry, yet qua…

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…
