Cava, and Liling Sun A quantum spin liquid is an exotic quantum state of matter that does not exhibit any classical magnetic ordered ground state. The realization of such a state in actual materials is of significant importance as it would provide a path to protected states for quantum information applications and also to Majorana fermions - both areas of vigorous current activity and interest in condensed matter physics. However, no solid evidence for the existence of such materials has been established in the laboratory, despite a decades-long search. Here, the authors report the pressure-induced melting of magnetic order and emergence of a new quantum state in α-RuCl 3 , a candidate compound in the proximity of a quantum spin-liquid state. The high-pressure phase is found to be extremely robust against applied pressure up to ~140 GPa. [Phys. Rev. B 97, 245149] Published Fri Jun 29, 2018
