Quantum Spin Liquids from a Materials Perspective

Quantum spin liquids are unique quantum states of matter predicted to arise in low-dimensional, frustrated, and quantum magnetic systems. Compared with conventional ferromagnetic and antiferromagnetic states, quantum spin liquids are expected to display a variety of novel and exotic properties, making their realization in materials a highly appealing prospect. While an unambiguous realization of this long-sought-after state remains elusive, a growing number of materials candidates show promise in revealing the properties of quantum spin liquids. In this review, we present some of the key challenges and current opportunities in the synthesis, characterization, and understanding of quantum spin liquids from the perspective of the broad and interdisciplinary field of materials research.
