Zarzuela Fernández, RicardoChudnovsky, Eugene M., 1948-Tejada Palacios, Javier2014-03-142014-03-142013-01-091098-0121https://hdl.handle.net/2445/51764Classical and quantum theory of spin waves in the vortex state of a mesoscopic submicron magnetic disk have been developed with account of the finite mass density of the vortex. Oscillations of the vortex core resemble oscillations of a charged string in a potential well in the presence of the magnetic field. A conventional gyrotropic frequency appears as a gap in the spectrum of spin waves of the vortex. The mass of the vortex has been computed, and the result agrees with experimental findings. The finite vortex mass generates a high-frequency branch of spin waves. The effects of an external magnetic field and dissipation have been addressed.11 p.application/pdfeng(c) American Physical Society, 2013SuperconductivitatPropietats magnètiquesFerromagnetismeSpin (Física nuclear)Teoria quànticaExcitació nuclearSuperconductivityMagnetic propertiesFerromagnetismNuclear spinQuantum theoryNuclear excitationinfo:eu-repo/semantics/article6213022014-03-14info:eu-repo/semantics/openAccess
