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 …

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

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 …

We present results from muon spin relaxation/rotation, magnetization, neutron scattering,
and transport measurements on polycrystalline samples of the pyrochlore iridates Y 2 Ir 2 O …

In the pyrochlore iridates R 2 Ir 2 O 7 (R= lanthanide, Y) determination of the magnetic
structure of the iridium moments remains an outstanding problem despite the role this is …

Motivated by the rapid experimental progress of quantum spin ice materials, we study the
dynamical properties of pyrochlore spin ice in the U (1) spin liquid phases. In particular, we …

The realization of quantum spin liquids on a triangular lattice magnet remains challenging
due to quenched disorders present in real materials. Here, we report local-probe signatures …

Electrical resistance is a crucial and well-understood property of systems ranging from
computer microchips to nerve impulse propagation in the human body. Here we study the …

We elucidate the ground state nature and low-energy spin dynamics of the s= 1/2 near-
perfect kagome antiferromagnet YCu 3 (OD) 6+ x Br 3− x (x= 0.5) using Cu 63 nuclear …

We report low-temperature specific heat and positive muon spin relaxation/rotation (μ SR)
measurements on both polycrystalline and single-crystal samples of the pyrochlore magnet …
