Direct Observation of Magnon Modes in Kagome Artificial Spin Ice with Topological Defects

V. S. Bhat, S. Watanabe, K. Baumgaertl +1

We investigate spin dynamics of artificial spin ice (ASI) where topological defects confine magnon modes in Ni${}_{81}$Fe${}_{19}$ nanomagnets arranged on an interconnected kagome latt…
