Frustration, the presence of competing interactions, is ubiquitous in the physical sciences
and is a source of degeneracy and disorder, which in turn gives rise to new and interesting …

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 …

Artificial spin ice arrays of micromagnetic islands are a means of engineering additional
energy scales and frustration into magnetic materials. Here we demonstrate a magnetic …

We propose the model which takes account of magnetocrystalline anisotropy effects in thin
magnetic films. The dimensionality crossover from two-dimensional monolayer to three …

We present a direct magnetic imaging study on the thermal macrospin ordering of artificial
kagome spin ice building blocks. Using photoemission electron microscopy, employing x-ray …

We have fabricated ultra-thin disc shaped islands wherein shape anisotropy confines the
moment to the island plane, creating XY-like superspins. At low temperatures, the …

The element-specific magnetization and ordering in trilayers consisting of 0.3–1.4
monolayer (ML) thick Fe layers embedded in Pd (001) has been determined using x-ray …

The interplay between topology and energy hierarchy plays a vital role in the collective
magnetic order in artificial ferroic systems. Here we investigate, experimentally, the effect of …

Postsynthetic, position‐selective addition of properties to materials constitutes a paradigm
shifting step in materials engineering. The approach enables creation of material systems …
