Competition between intermediate plaquette phases in SrCu${}_2$(BO${}_3$)${}_2$ under pressure

C. Boos, S. P. G. Crone, I. A. Niesen +3

Building on the growing evidence based on NMR, magnetization, neutron scattering, ESR, and specific heat that, under pressure, SrCu${}_2$(BO${}_3$)${}_2$ has an intermediate phase betwee…
