Description
Summary:We have studied the pressure-induced quantum phase transition in the singlet-ground-state antiferromagnet CsFeCl3. Neutron diffraction experiments under pressure evidence the magnetic long-range order at low temperatures. Magnetic structure analysis reveals a 120∘ structure with a propagation vector of kmag=(1/3,1/3,0). The estimated critical exponent of the order parameter suggests that CsFeCl3 belongs to the universality class of U(1)×Z2 symmetry which is expected to realize the chiral liquid state.
