Magnons and Phonons Optically Driven out of Local Equilibrium in a Magnetic Insulator
Magnons and Phonons Optically Driven out of Local Equilibrium in a Magnetic Insulator
Magnons are the energy quanta of fundamental spin excitations, namely spin waves, and they can make a considerable contribution to energy transport in some magnetic materials in a similar manner as lattice vibration waves or phonons. The coupling and possible non-equilibrium between magnons and other energy carriers have been used …
