@article{Kodama2004FieldinducedEO, title={Field-induced effects of anisotropic magnetic interactions in SrCu2(BO3)2}, author={Kazuto Kodama and Shin Miyahara and Masashi Takigawa and M. Horvati{\'c} and Claude Berthier and Fr{\'e}d{\'e}ric Mila and Hiroshi Kageyama and Yutaka Ueda}, journal={Journal of Physics: Condensed Matter}, year={2004}, volume={17}, pages={L61 - L68} }

We observed a field-induced staggered magnetization in the 2D frustrated dimer singlet spin system SrCu2(BO3)2 by 11B NMR, from which the magnitudes of the intradimer Dzyaloshinsky–Moriya interaction and the staggered g-tensor were determined. These anisotropic interactions cause singlet–triplet mixing and eliminate a quantum phase transition at the expected critical field Hc for gap closing. They provide a quantitative account for some puzzling phenomena such as the onset of a uniform…
