    Itinerant magnetic excitations in antiferromagnetic CaFe2As2 

    Diallo, S. O.; Antropov, V. P.; Perring, T.G.; Broholm, C.; Pulikkotil, J. J.; Ni, N.; Bud'ko, S.L.; Canfield, P.C.; Kreyssig, A.; Goldman, A. I.; McQueeney, R. J. (American Physical Society, 2009-05-08)
    Neutron scattering measurements of the magnetic excitations in single crystals of antiferromagnetic CaFe2As2 reveal steeply dispersive and well-defined spin waves up to an energy of ~100 meV. Magnetic excitations above 100 ...

    A strongly fluctuating quasi-two-dimensional insulator 

    Cooper, A.S.; Espinosa, G.P.; Broholm, C.; Aeppli, G. (American Institute of Physics, 1991-04-15)
    The authors describe neutron-scattering data for SrCr8-xGa4+xO19, a layered compound containing planes of S=3/2 Cr3+ ions which form Kagome lattices. Despite strong antiferromagnetic interactions (θCW≈-500 K), fluctuations ...

    From cooperative paramagnetism to Neel order in Y2Ru2O7: neutron scattering measurements 

    van Duijn, J.; Hur, N.; Taylor, J. W.; Qiu, Y.; Huang, Q.Z.; Cheong, S.-W.; Broholm, C.; Perring, T.G. (American Physical Society, 2008-01-01)
    Spin correlations in the pyrochlore antiferromagnet Y2Ru2O7 with Curie-Weiss temperature ΘCW* - 1100 K and critical temperature TN = 77 K were examined through neutron scattering. For TN < T < ΘCW / 3 the data show spin ...

    S=½ chain in a staggered field: high-energy bound-spinon state and the effects of a discrete lattice 

    Kenzelmann, M.; Batista, C. D.; Chen, Y.; Broholm, C.; Reich, D.H.; Park, S.; Qiu, Y. (American Physical Society, 2005-03-01)
    We report an experimental and theoretical study of the antiferromagnetic S=½ chain subject to uniform and staggered fields. Using inelastic neutron scattering, we observe a bound-spinon state at high energies in the linear ...

    Quantum criticality in an organic magnet 

    Stone, M. B.; Broholm, C.; Reich, D.H.; Tchernyshyov, O.; Vorderwisch, P.; Harrison, N. (American Physical Society, 2006-06-30)
    Exchange interactions between S=½ sites in piperazinium hexachlorodicuprate produce a frustrated bilayer magnet with a singlet ground state. We have determined the field-temperature phase diagram by high field magnetization ...

    Spin resonance in the d-wave superconductor CeCoIn5 

    Stock, C.; Broholm, C.; Hudis, J.; Kang, H. J.; Petrovic, C. (American Physical Society, 2008-02-29)
    Neutron scattering is used to probe antiferromagnetic spin fluctuations in the d-wave heavy fermion superconductor CeCoIn5 (Tc=2.3 K). Superconductivity develops from a state with slow (ℎΓ=0.3±0.15 meV) commensurate ...

    Spinons in the strongly correlated copper oxide chains in SrCuO2 

    Broholm, C.; Perring, T.G.; Takagi, H.; Frost, C. D.; Zaliznyak, L.A.; Woo, H. (American Physical Society, 2004-08-20)
    We have investigated the spin dynamics in the strongly correlated chain copper oxide SrCuO2 for energies up to ≥0.6 eV using inelastic neutron scattering. We observe a gapless continuum of magnetic excitations, which is ...

    Central mode and spin confinement near the boundary of the superconducting phase in YBa2Cu3O6.353 (Tc=18 K) 

    Birgeneau, R. J.; Broholm, C.; Liang, R.; Yamani, Z.; Bonn, D.; Tun, Z.; Chung, J.-H.; Hardy, W. N.; Stock, C.; Buyers, W.J.L. (American Physical Society, 2006-03-01)
    We have mapped the neutron scattering spin spectrum at low energies in YBa2Cu3O6.353 (Tc=18 K), where the doping ~0.06 is near the critical value (pc=0.055) for superconductivity. No coexistence with long-range-ordered ...

    Coupled Magnetic and Ferroelectric Domains in Multiferroic Ni3V2O8 

    Chen, W. C.; Kenzelmann, M.; Gentile, T. R.; Chen, Y.; Cabrera, I.; Rogado, N.; Lawes, G.; Broholm, C.; Lynn, J. W.; Erwin, R.; Cava, R.J.; Leao, J. B. (American Physical Society, 2009-08-21)
    Electric control of multi-ferroic domains is demonstrated through polarized magnetic neutron diffraction. Cooling to the cycloidal multi-ferroic phase of Ni3V2O8 in an electric field E causes the incommensurate Bragg ...

    Bound spinons in an antiferromagnetic S=1/2 chain with a staggered field 

    Kenzelmann, M.; Chen, Y.; Broholm, C.; Reich, D.H.; Qiu, Y. (American Physical Society, 2004-07-02)
    Inelastic neutron scattering was used to measure the magnetic field dependence of spin excitations in the antiferromagnetic S=1/2 chain CuCl2·2(dimethylsulfoxide) in the presence of uniform and staggered fields. Dispersive ...
