Abstract / Description:Nuclear magnetic resonance (NMR) experiments have been performed on the
quasi-two-dimensional quantum spin system SrCu2(BO3)(2). The Cu NMR
spectrum in the 1/8-magnetization plateau state at 27.6 T and 35 mK
shows fine structure, providing clear evidence for a magnetic
superlattice in the plateau state. We conclude that the superlattice
has a rhomboid unit cell with oscillating spin polarization, which is
in good agreement with the numerical calculation on the
Shastry-Sutherland spin model. (C) 2003 Elsevier B.V. All rights
