Coexistence of ferromagnetic and stripe antiferromagnetic spin fluctuations in SrCoAs
Yu Li, Zhiping Yin, Zhonghao Liu +16
We use inelastic neutron scattering to study energy and wave vector dependence of spin fluctuations in SrCoAs, derived from SrFeCoAs iron pnictide supercond…
Fractional excitations in the square-lattice quantum antiferromagnet
B. Dalla Piazza, M. Mourigal, N. B. Christensen +7
The square-lattice quantum Heisenberg antiferromagnet displays a pronounced anomaly of unknown origin in its magnetic excitation spectrum. The anomaly manifests itself only for sho…
Nematic spin fluid in the tetragonal phase of BaFe2As2
Leland W. Harriger, Huiqian Luo, Mengshu Liu +5
Magnetic interactions are generally believed to play a key role in mediating electron pairing for superconductivity in iron arsenides; yet their character is only partially underst…
Anomalous High-Energy Spin Excitations in La2CuO4
N. S. Headings, S. M. Hayden, R. Coldea +1
Inelastic neutron scattering is used to investigate the collective magnetic excitations of the high-temperature superconductor parent antiferromagnet La2CuO4. We find that while th…
Confinement of fractional quantum number particles in a condensed matter system
B. Lake, A. M. Tsvelik, S. Notbohm +6
The idea of confinement states that in certain systems constituent particles can be discerned only indirectly being bound by an interaction whose strength increases with increasing…
Testing the itinerancy of spin dynamics in superconducting Bi2212
Guangyong Xu, G. D. Gu, M. Hucker +4
Much of what we know about the electronic states of high-temperature superconductors is due to photoemission and scanning tunneling spectroscopy studies of the compound Bi2212. The…
