Book 2021 of the current understanding of the field, both on the theoretical and experimental levels, written by leading experts. The book is written in a linear way with very few prerequisites. It also contains textbook-like descriptions of theoretical methods to help advanced students and researchers to enter the field.

Experimental Search for Quantum Spin Ice,O. (. = Sn, Ti), Tb.O. (. = Sn, Ti) and Pr.O. (. = Sn, Zr, Ir, Hf) all display properties consistent with a dynamic version of spin ice, but their lowest temperature properties are not yet understood. The status of the current literature on these materials is reviewed here.

Analytical Approaches to Quantum Spin Ice, to derive the general Hamiltonian for pyrochlore spin systems and to find its classical phase diagram purely from symmetry considerations. This enables us to express the conditions for a pyrochlore magnet to be in its ground state in terms of a general local constraint, of which the “ice rule” known from spin ice is a special case.

A Kasteleyn transition predicted for the former case is not observed in actual compounds probably due to the slow spin dynamics, while a ferromagnetic transition of sublattice spins are found for magnetic fields between [111] and [112].
