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 …

Despite their simple formulation, short-range classical antiferromagnetic Ising models on
frustrated lattices give rise to exotic phases of matter, in particular, due to their macroscopic …

Spin and spatial dimensionalities are universal concepts, essential for describing both
phase transitions and dynamics in magnetic materials. Lately, these ideas have been …

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 …

Geometry in materials is a key concept which can determine material behavior in ordering,
frustration, and fragmentation. More specifically, the behavior of interacting degrees of …

We demonstrate an experimental realization of the short range magnetic order in a one-
dimensional Ising chain using fabricated mesospins. We confirm an excellent agreement …
