  • Abstract
    In this work, we have fabricated two types of artificial square spin ice structures and probed their dynamic behaviors using broadband ferromagnetic resonance (FMR) spectroscopy. We observed a drastic change in the resonance frequency at remanence state due to the modification of magnetization ground state comparing the two types of structures. The angular dependence of resonance frequencies in saturated state is also observed for both structures.
