Twisted magnon frequency combs in ferromagnetic nanorings
The study investigates twisted magnon frequency combs (tMFCs) in ferromagnetic nanorings using micromagnetic simulations. The researchers found that hole size and external magnetic fields can tune the comb spacing and density. Enlarging the hole introduces new modes, while an in-plane field enables reversible tuning, establishing nanorings as a versatile platform for nonlinear magnonics.
