Transverse instabilities of multiple vortex chains in superconductor-ferromagnet bilayers

G. Karapetrov, M. V. Milošević, M. Iavarone +4

Using scanning tunneling microscopy and Ginzburg-Landau simulations we explore vortex configurations in magnetically coupled NbSe${}_2$-Permalloy superconductor-ferromagnet bilayer.…
