Molecular spin-orbit excitations in the J_eff = 1/2 frustrated spinel GeCoO
K. Tomiyasu, M. K. Crawford, D. T. Adroja +9
We describe powder and single-crystal inelastic neutron scattering experiments on a spinel-type antiferromagnet GeCoO, represented by an effective total angular momentum J_…
Incommensurate spin correlations induced by magnetic Fe ions substituted into overdoped Bi1.75Pb0.35Sr1.90CuO6+z
H. Hiraka, Y. Hayashi, S. Wakimoto +12
Spin correlations in the overdoped region of Bi1.75Pb0.35Sr1.90CuO6+z have been explored with Fe-doped single crystals characterized by neutron scattering, muon-spin-rotation (muSR…
Similar glassy features in the NMR response of pure and disordered La1.88Sr0.12CuO4
V. F. Mitrovic, M. -H. Julien, C. de Vaulx +4
High Tc superconductivity in La2-xSrxCuO4 coexists with (striped and glassy) magnetic order. Here, we report NMR measurements of the 139La spin-lattice relaxation, which displays a…
Coherent quasi-particles-to-incoherent hole-carriers crossover in underdoped cuprates
M. Hashimoto, T. Yoshida, K. Tanaka +7
In underdoped cuprates, only a portion of the Fermi surface survives as Fermi arcs due to pseudogap opening. In hole-doped LaCuO, we have deduced the "coherence temperatu…
The Fincher-Burke spin excitations and omega/T scaling in the insulating 5% Sr-doped La2CuO4
Wei Bao, Ying Chen, K. Yamada +4
Insulating La1.95Sr0.05CuO4 shares with superconducting cuprates the same Fincher-Burke-like spin excitations, which usually are observed in itinerant antiferromagnets. The local s…
Dispersion of the high-energy phonon modes in NdCeCuO
M. Braden, L. Pintschovius, T. Uefuji +1
The dispersion of the high-energy phonon modes in the electron doped high-temperature superconductor NdCeCuO has been studied by inelastic neutron scattering.…
