Artificial spin ices consist of nanomagnets arranged on the sites of various periodic and
aperiodic lattices. They have enabled the experimental investigation of a variety of …

Quantum spin liquids may be considered'quantum disordered'ground states of spin systems,
in which zero-point fluctuations are so strong that they prevent conventional magnetic long …

The experimental technique of ac susceptibility can be used as a probe of magnetic
dynamics in a wide variety of systems. Its use is restricted to the low-frequency regime and …

The long fascination that antiferromagnetic materials has exerted on the scientific community
over about a century has been entirely renewed recently with the discovery of several …

The family of magnetic rare-earth pyrochlore oxides R 2 M 2 O 7 plays host to a diverse
array of exotic phenomena, driven by the interplay between geometrical frustration and spin …

The frustrated pyrochlore magnet Yb 2 Ti 2 O 7 has the remarkable property that it orders
magnetically but has no propagating magnons over wide regions of the Brillouin zone. Here …

This contribution provides a thorough examination of the structural characteristics of
pyrochlore-type lanthanide titanates and zirconates Ln 2 Ti 2 O 7 and Ln 2 Zr 2 O 7, across …

The spin-1/2 triangular lattice antiferromagnet YbMgGaO 4 has attracted attention recently
as a quantum spin-liquid candidate with the possible presence of off-diagonal anisotropic …

Hedgehog and antihedgehog spin textures in magnets behave as emergent monopoles and
antimonopoles, which give rise to astonishing transport and electromagnetic phenomena …

Extensive experimental investigations of the magnetic structures and excitations in the XY
pyrochlores have been carried out over the past decade. Three families of XY pyrochlores …
