Abstract: As the magnetic field penetrates the surface of a superconductor, it results in the formation of flux vortices. It has been predicted that the flux vortices will have a charged vortex core and create a… read more here.

DOI: 10.1134/s0021364024603439
Abstract: We study the magnon spectrum in a thin ferromagnet–superconductor heterostructure in the presence of a single superconducting vortex. We employ the Bogolubov–de Gennes Hamiltonian which describes the magnons in the presence of the stray magnetic… read more here.
