Chiral magnonic edge states in ferromagnetic skyrmion crystals controlled by magnetic fields
Sebastián A. Díaz, Tomoki Hirosawa, Jelena Klinovaja, Daniel Loss
Abstract
The authors show that a ferromagnetic skyrmion crystal provides a novel platform for switchable magnon currents. Taking advantage of a topological phase transition in the magnon spectrum, an external magnetic field can turn on and off chiral magnon currents carried by topological edge states
