Electron states in a planar 2D ferromagnet: combined spin-orbit symmetry and half-integer orbital angular momentum of an electron
Ramazashvili R. R. Jr.
The electron states in a planar 2D ferromagnet with a spatially nonuniform distribution of the order parameter are analyzed. When a magnetic field is imposed on the system, electron states with a half-integer orbital angular momentum arise near topological defects (vortices). The shape and temperature dependence of the ESR intensity in the vortex states are discussed.
