Curvature-induced stabilization and field-driven dynamics of magnetic hopfions in toroidal nanorings
(NLM (Medline), 2023-02-09)
Three dimensional magnetic textures are a cornerstone in magnetism research. In this work, we analyze the stabilization and dynamic response of a magnetic hopfion hosted in a toroidal nanoring with intrinsic Dzyaloshinskii-Moriya ...
Wave reversal mode: A new magnetization reversal mechanism in magnetic nanotubes
(Elsevier Science, 2020-03)
We have investigated the magnetic properties of 14 nm thick and 1 μm long nickel and permalloy nanotubes with external diameters of 40 and 100 nm as a function of the angle θ at which the external magnetic field is applied. ...
Confinement of Dirac electrons in graphene magnetic quantum dots
(IOP Publishing, 2018-08-13)
We characterize the confinement of massless Dirac electrons under axially symmetric magnetic fields in graphene, including zero energy modes and higher energy levels. In particular, we analyze in detail the Aharonov-Casher ...
Magnetostatic Modes in Samples With Inhomogeneous Internal Fields
(IEEE, 2015)
Magnetostatic modes in ferromagnetic samples have been studied systematically since the 1950s. They are very well characterized and understood in samples with uniform internal magnetic fields. More recently, interest has ...
Compact modes in quasi one dimensional coupled magnetic oscillators
(IOP Publishing Ltd., 2017)
In this work we study analytically and numerically the spectrum and localization properties of three quasi-one-dimensional (ribbons) split-ring resonator arrays which possess magnetic flatbands, namely, the stub, Lieb and ...
Quasinormal modes of black holes immersed in a strong magnetic field
(ELSEVIER SCIENCE BV, 2008)
We found quasinormal modes, both in time and frequency domains, of the Ernst black holes, that is neutral black holes immersed in an external magnetic field. The Ernst solution reduces to the Schwarzschild solution, when ...
