The spin ice materials, including Ho 2 Ti 2 O 7 and Dy 2 Ti 2 O 7, are rare-earth pyrochlore
magnets which, at low temperatures, enter a constrained paramagnetic state with an …

Frustration in magnetic materials arising from competing exchange interactions can prevent
the system from adopting long-range magnetic order and can instead lead to a diverse …

The spin ice compounds Dy2Ti2O7 and Ho2Ti2O7 are highly unusual magnets that
epitomize a set of concepts of great interest in modern condensed matter physics: Their low …

This review is a study of how the idea of spin ice has evolved over the years, with a focus on
the scientific questions that have come to define the subject. Since our initial discovery of …

Fractals—objects with noninteger dimensions—occur in manifold settings and length scales
in nature. In this work, we identify an emergent dynamical fractal in a disorder-free …

The Coulomb phase, with its dipolar correlations and pinch-point–scattering patterns, is
central to discussions of geometrically frustrated systems, from water ice to binary and mixed …

Complex behavior poses challenges in extracting models from experiment. An example is
spin liquid formation in frustrated magnets like Dy2Ti2O7. Understanding has been hindered …

The discovery of the spin-ice phase in Dy2Ti2O7 numbers among the most significant
findings in magnetic materials in over a decade,,. Spin ice has since been associated with …

The instruments best suited to performing high-energy-resolution neutron spectroscopy are
spin-echo spectrometers and backscattering spectrometers. The development of these …

At low temperatures, spin ice is populated by a finite density of magnetic monopoles—
pointlike topological defects with a mutual magnetic Coulomb interaction. We discuss the …
