    • 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 ...
    • Evidence for decay of spin waves above the pseudogap of underdoped YBa2Cu3O6.35 

      Stock, C.; Cowley, R.A.; Buyers, W.J.L.; Coldea, R.; Broholm, C.; Frost, C.D.; Birgeneau, R.J.; Liang, R.; Bonn, D.; Hardy, W.N. (American Physical Society, 2007-05-01)
      The magnetic spectrum at high energies in heavily underdoped YBa2Cu3O6.35 (Tc=18 K) has been determined throughout the Brillouin zone. At low energy, the scattering forms a cone of spin excitations emanating from the ...
    • 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 ...
