Spin wave spectral probing of degenerate microstates in building-block of square artificial spin ice

We have investigated the spin wave modes of dipolar coupled, highly shape anisotropic magnetic nanoislands forming square artificial spin ice system by performing micromagnetic simulations using MuMax3 in combination with Matlab coding. Here, artificial spin ice is considered to be formed by the fou...
