"Magnetic Gradient" edge magnetoplasmons in non-uniform magnetic field
| Resumo: | It is shown that laterally inhomogeneous strong magnetic field applied to otherwise spatially homogeneous two-dimensional electron system (2DES) allows "magnetic gradient" or special magnetic-edge magnetoplasmons (MEMPs). This mechanism is different from usual "density gradient" edge magnetoplasmons. Symmetric and antisymmetric families of MEMPs are obtained. They are localized at magnetic field inhomogeneity (magnetic-edge). Both symmetric and antisymmetric MEMPs have the modes of opposite chirality. |
