Intermode depolarization correlation of magnons

Yokoi, Naoto*; Saito, Eiji

Multimode magnon dynamics affected by demagnetizing fields has been discussed in terms of a Hamiltonian approach. In the multimode dynamics involving magnetization relaxation, inter-mode correlation of magnons is found to be formed spontaneously. The correlation suppresses the transverse magnetization dynamics, giving rise to depolarization correlation (DPC) of magnons. DPC may subsist in equilibrium distribution at finite temperatures.
