Crystal symmetry and high-magnetic-field specific heat of SrCu 2(BO 3) 2

We report measurements of the specific heat of the quantum spin liquid system SrCu 2(BO 3) 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 neares...
