Abstract: Characterization of a quantum spin liquid Theoretical predictions of the existence of an exotic state of matter called a quantum spin liquid have been supported by experimental evidence, but many fundamental questions about this novel state remain unanswered. Quantum spin liquids can occur in an insulator with strongly interacting magnetic units when the usual symmetry-breaking magnetically ordered state at low temperatures is avoided as a result of quantum fluctuations. An advanced magnetic probing technique, called muon spin relaxation, has now been used to study the molecular layered system κ-(BEDT-TTF)2Cu2(CN)3, widely regarded as a prime example of a quantum spin liquid. Using implanted muons as a sensitive local magnetic probe, the authors show that magnetic order can be recovered in this system by applying a very small magnetic field. A complex phase diagram is revealed for the spin liquid, which demonstrates the delicate balance between the spin liquid and magnetic phases.
