Artificial spin ices consist of nanomagnets arranged on the sites of various periodic and
aperiodic lattices. They have enabled the experimental investigation of a variety of …

Pursuing topological phases in natural and artificial materials is one of the central topics in
modern physical science and engineering. In classical magnetic systems, spin waves (or …

We predict the emergence of second-order topological insulators in the dynamics of spin-
texture-based metamaterials. We propose that the quantized Chern number and the Z 6 …

Pursuing topological phase and matter in a variety of systems is one central issue in current
physical sciences and engineering. Motivated by the recent experimental observation of …

We study the topological phase in a dipolar-coupled two-dimensional breathing square
lattice of magnetic vortices. By evaluating the quantized Chern number and Z 4 Berry phase …

We use nano disk arrays with square and honeycomb symmetry to investigate magnetic
phases and spin correlations of XY dipolar systems at the micro scale. Utilizing …

Topological excitations in periodic magnetic crystals have received significant recent
attention. However, their fate once the lattice periodicity is broken is an open question. In this …

Spin waves with wavelengths in the nanometre range could serve as data carriers in future
magnonic logic or signal processing devices. We investigate the interference of spin waves …

We report on spin-vortex pair dynamics measured at temperatures low enough to suppress
stochastic core motion, thereby uncovering the highly nonlinear intrinsic dynamics of the …

Recent acoustic and electrical-circuit experiments have reported the third-order (or octupole)
topological insulating phase, while its counterpart in classical magnetic systems has yet to …
