Magnetic structure in the one-third magnetization plateau phase of a triangular quantum magnet

Abstract: We propose single crystal diffraction measurements to probe the magnetic structure in the 1/3rd magnetization plateau phase observed for fields in the range 10-15 T in the triangular quantum (S=1/2) antiferromagnet Ba3CoSb2O9. Magnetization plateau phases are conceptually very interesting as their stability (why magnetization is constant in a varying applied magnetic field) cannot be understood at a mean-field level, collective zero-point quantum fluctuations are required to stabilize such phases. We plan to experimentally test theoretical proposals that the magnetic structure has collinear up-up-down order polarized along the field with a strong ordered moment reduction. Those studies are complementary to our inelastic neutron scattering studies of crystal field transitions and quantum effects in the low-energy spin dynamics.
