Dimensional crossover in a spin liquid to helimagnet quantum phase transition

Abstract

Neutron scattering is used to study magnetic field induced ordering in the quasi-1D quantum spin-tube compound Sul--Cu${}_2$Cl${}_4$ that in zero field has a non-magnetic spin-liquid ground state. The experiments reveal an incommensurate chiral high-field phase stabilized by a geometric frustration of the magnetic interactions. The measured critical exponents $\beta \approx 0.235$ and $\nu \approx 0.34$ at $H_c\approx 3.7$ T point to an unusual sub-critical scaling regime and may reflect the chiral nature of the quantum critical point.
