Spin Dynamics, Loop Formation and Cooperative Reversal in Artificial Quasicrystals with Tailored Exchange Coupling
Vinayak Shantaram Bhat, Sho Watanabe, Florian Kronast +2
Aperiodicity and un-conventional rotational symmetries allow quasicrystalline structures to exhibit unprecedented physical and functional properties. In magnetism, artificial ferro…
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 NiFe nanomagnets arranged on an interconnected kagome latt…
Angular Dependent Magnetization Dynamics with Mirror-symmetric Excitations in Artificial Quasicrystalline Nanomagnet Lattices
V. S. Bhat, D. Grundler
We report angle-dependent spin-wave spectroscopy on aperiodic quasicrystalline magnetic lattices, i.e., Ammann, Penrose P2 and P3 lattices made of large arrays of interconnected Ni…
Textured heterogeneity in square artificial spin ice
J. C. T Lee, S. K. Mishra, V. S. Bhat +8
We report evidence of spontaneous formation of a heterogeneous network of superdomains in two-dimensional square artificial spin ice nanostructures in externally applied magnetic f…
Angular Dependent Magnetization Dynamics of Kagome Artificial Spin Ice Incorporating Topological Defects
V. S. Bhat, F. Heimbach, I. Stasinopoulos +1
We report angular-dependent spin-wave spectroscopy on kagome artificial spin ice made of large arrays of interconnected Ni80Fe20 nanobars. Spectra taken in saturated and disordered…
Magnetization Dynamics of Topological Defects and the Spin Solid in Kagome Artificial Spin Ice
V. S. Bhat, F. Heimbach, I. Stasinopoulos +1
We report broadband spin-wave spectroscopy on kagome artificial spin ice (ASI) made of large arrays of interconnected NiFe nanobars. Spectra taken in saturated and di…
