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 …

Frustrated magnets are materials in which localized magnetic moments, or spins, interact
through competing exchange interactions that cannot be simultaneously satisfied, giving rise …

In this review, we provide an introduction to the physics of a series of frustrated quantum rare-
earth pyrochlores. We first give a background on the microscopic single-and two-ion physics …

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 …

YbMgGaO 4, a structurally perfect two-dimensional triangular lattice with an odd number of
electrons per unit cell and spin-orbit entangled effective spin-1/2 local moments for the Yb …

A frustrated system is one whose symmetry precludes the possibility that every pairwise
interaction (“bond”) in the system can be satisfied at the same time. Such systems are …

Within the past 20 years or so, there has occurred an explosion of interest in the magnetic
behavior of pyrochlore oxides of the type A 2 3+ B 2 4+ O 7, where A is a rare-earth ion and …

Frustrated quantum magnets are expected to host many exotic quantum spin states like
quantum spin liquid (QSL), and have attracted numerous interest in modern condensed …

Frustration, defined as a competition between interactions such that not all of them can be
satisfied, is important in systems ranging from neural networks to structural glasses …

Disordered magnetic states known as spin liquids are of paramount importance in both
fundamental and applied science. A classical state of this kind was predicted for the Ising …
