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…

Dynamics and Instabilities of the Shastry-Sutherland Model.

TLDR
The excitation spectrum in the dimer phase of the Shastry-Sutherland model is studied by using an unbiased variational method that works in the thermodynamic limit and finds four different instabilities: antiferro spin nematic, plaquette spin nematics, stripe magnetic order, and plaquettes order.

Dzyaloshinski-Moriya interaction in the 2D spin gap system SrCu(2)(BO(3))(2).

TLDR
A new mechanism for the observed ESR transitions forbidden by standard selection rules is proposed, which relies on an instantaneous Dzyaloshinski-Moriya interaction induced by spin-phonon couplings.
