Lithographic processing and film growth technologies are continuing to advance, so that it is
now possible to create patterned ferroic materials consisting of arrays of sub-1 μm elements …

Two-dimensional artificial spin-ice systems constructed from arrays of dipolar coupled
monodomain magnets offer an experimental route to study the physics of frustration and a …

Artificial spin ice systems have been proposed as a playground for the study of monopole-
like magnetic excitations,, similar to those observed in pyrochlore spin ice materials …

The modification of geometry and interactions in two-dimensional magnetic nanosystems
has enabled a range of studies addressing the magnetic order,,,,–, collective low-energy …

Over the past few years, the study of magnetization dynamics in artificial spin ices has

Two-dimensional arrays of interacting magnetic nanostructures offer a remarkable
playground for simulating, experimentally, lattice spin models. Initially designed to capture …

Recently there has been intense interest in kagome metals, which are expected to host flat
bands (FBs). However, the observed “FBs” are not flat over the whole two-dimensional …

Geometrical frustration is a condition that occurs when a material's lattice geometry
precludes minimizing the energy of all the interactions among pairs of neighbors …
