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…
Comment on "Onset of Boson Mode at the Superconducting Critical Point of Underdoped YBa2Cu3Oy"
Yoichi Ando
In a recent Letter [Phys. Rev. Lett. 97, 207001 (2006)], Doiron-Leyraud et al. reported a study of low-temperature thermal conductivity of underdoped YBa2Cu3Oy across the supercond…
Implication of the Mott-limit violation in high-Tc cuprates
Yoichi Ando
The Fermi arc is a striking manifestation of the strong-correlation physics in high-T_c cuprates. In this paper, implications of the metallic transport in the lightly hole-doped re…
Quantum Phase Transition in the Normal State of High-Tc Cuprates at Optimum Doping
F. F. Balakirev, J. B. Betts, A. Migliori +3
By using a 60 T magnetic field to suppress superconductivity in La2-pSrpCuO4, (LSCO) we reveal an anomalous peak in the Hall number, located at optimum doping and developing at tem…
Observation of a 500meV Collective Mode in LaSrCuO and NdCuO
J. P. Hill, G. Blumberg, Young-June Kim +9
Utilizing resonant inelastic x-ray scattering, we report a previously unobserved mode in the excitation spectrum of LaSrCuO at 500 meV. The mode is peaked around th…
Peculiar Ferrimagnetism Associated with Charge Order in Layered Perovskite GdBaMn2O5
A. A. Taskin, Yoichi Ando
The magnetic properties of GdBaMn_{2}O_{5.0}, which exhibits charge ordering, are studied from 2 to 400 K using single crystals. In a small magnetic field applied along the easy ax…
