Lisainfo

Received: 4 October 2004; revised: 19 November 2004; published: 23 March 2005 We report measurements of the specific heat of them quantum spin liquid system SrCu2(BO3)(2) in continuous magnetic fields H of up to 33 T. The specific heat data, when combined with a finite temperature Lanczos diagonalization of the Shastry-Sutherland Hamiltonian, indicate the presence of a nearest neighbor Dzyaloshinsky-Moriya (DM) interaction that violates the crystal symmetry. Moreover, the same DM interaction is required to explain the observed electron spin resonance lines for H vertical bar vertical bar c.
