The experimental data demonstrate that a phase transition from the quantum-disordered spin-liquid phase to the long-range ordered antiferromagnetic phase with the Néel temperature T N=6K is induced at P=2.5GPa. The observed decrease of T N upon compression correlates with the anomalies in pressure behavior of Cu-O bond length and Cu-O-Cu bond angles. The reasons for the observed spin-freezing transition are discussed within the framework of the available theoretical models and the recent observation of the field-induced spin freezing. © 2012 American Physical Society. 2015-04-24 14:58:21 untagged Physical Sciences not elsewhere classified
