Since it was first demonstrated in 1987, magnetic force microscopy (MFM) has become a
truly widespread and commonly used characterization technique that has been applied to a …

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 …

This article reviews odd-frequency (odd-ω) pairing with a focus on superconducting systems.
Since Berezinskii introduced the concept of odd-frequency order in 1974 it has been viewed …

Free monopoles have fascinated and eluded researchers since their prediction by Dirac in
1931. In spin ice, the bulk frustrated magnet, local ordering principles known as ice rules …

In the last twenty years, numerical modeling has become an indispensable part of
magnetism research. It has become a standard tool for both the exploration of new systems …

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 …

Recent advances in nanotechnology allow model systems to be constructed, in which
frustrated interactions can be tuned at will, such as artificial spin ice. The symmetry of the …

Recently, significant interest has emerged in fabricated systems that mimic the behavior of
geometrically frustrated materials. We present the full realization of such an artificial spin ice …

We analyze an array of linearly extended monodomain dipoles forming square and kagome
lattices. We find that its phase diagram contains two (distinct) finite-entropy kagome ice …

Artificial spin ices are frustrated spin systems that can be engineered, in which fine tuning of
geometry and topology has allowed the design and characterization of exotic emergent …
