Cs 2 CuCl 4 is known to possess a quantum spin-liquid phase with antiferromagnetic interaction below 2.8 K. We report the observation of a new metastable magnetic phase of the triangular frustrated quantum spin system Cs 2 CuCl 4 induced by the application of hydrostatic pressure. We measured the magnetic properties of Cs 2 CuCl 4 following the application and release of pressure after 3 days. We observed a previously unknown ordered mag-netic phase with a transition temperature of 9 K. Furthermore, the recovered sample with new magnetic ground state possesses an equivalent crystal structure to the uncompressed one with antiferromagnetic quantum spin-liquid phase.
