Quantum Spin Excitations through the metal-to-insulator crossover in
Shiliang Li, Zahra Yamani, Hye Jung Kang +5
We use inelastic neutron scattering to study the temperature dependence of the spin excitations of a detwinned superconducting YBaCuO ( K). In contrast to…
Neutron and X-ray diffraction study of cubic [111] field cooled Pb(Mg1/3Nb2/3)O3
C. Stock, Guangyong Xu, P. M. Gehring +6
Neutron and x-ray diffraction techniques have been used to study the competing long and short-range polar order in the relaxor ferroelectric Pb(MgNb)O (PMN) u…
Spin resonance in the d-wave superconductor CeCoIn5
C. Stock, C. Broholm, J. Hudis +2
Neutron scattering is used to probe antiferromagnetic spin fluctuations in the d-wave heavy fermion superconductor CeCoIn (T=2.3 K). Superconductivity develops from a s…
Magnetic and orbital ordering in the spinel MnV2O4
V. O. Garlea, R. Jin, D. Mandrus +5
Neutron inelastic scattering and diffraction techniques have been used to study the MnV2O4 spinel system. Our measurements show the existence of two transitions to long-range order…
Magnetism and structure of LixCoO2 and comparison to NaxCoO2
J. T. Hertz, Q. Huang, T. McQueen +4
The magnetic properties and structure of LixCoO2 for x between 0.5 and 1.0 are reported. Co4+ is found to be high-spin in LixCoO2 for x between 0.94 and 1.0 and low-spin for x betw…
Gapped itinerant spin excitations account for missing entropy in the hidden order state of URuSi
C. R. Wiebe, J. A. Janik, G. J. Macdougall +9
One of the primary goals of modern condensed matter physics is to elucidate the nature of the ground state in various electronic systems. Many correlated electron materials, such a…
