Fermi-liquid ground state in n-type copper-oxide superconductor Pr0.91Ce0.09LaCuO4-y
G. -q. Zheng, T. Sato, Y. Kitaoka +2
We report nuclear magnetic resonance studies on the low-doped n-type copper-oxide Pr_{0.91}LaCe_{0.09}CuO_{4-y} (T_c=24 K) in the superconducting state and in the normal state unco…
Commensurate spin dynamics in the superconducting state of an electron-doped cuprate superconductor
K. Yamada, K. Kurahashi, T. Uefuji +4
We report neutron scattering studies on single crystals of the electron-doped (n-type) superconducting cuprate Nd2-xCexCuO4 (x=0.15) with Tc = 18 K and 25 K. Unlike the hole-doped…
Angle-resolved photoemission spectroscopy of Na-doped Ca2CuO2Cl2 single crystals: Fingerprints of a magnetic insulator in a heavily underdoped superconductor
Y. Kohsaka, T. Sasagawa, F. Ronning +7
Electronic evolution from an antiferromagnet to a high-Tc superconductor is revealed by angle-resolved photoemission experiments on tetragonal Ca(1.9)Na(0.1)CuO(2)Cl(2) single crys…
Spin Pseudo Gap in La2-xSrxCuO4 Studied by Neutron Scattering
C. H. Lee, K. Yamada, H. Hiraka +2
Spin excitations of La2-xSrxCuO have been studied using inelastic neutron scattering techniques in the energy range of 2 meV =< w =< 12 meV and the temperature range of 8 K =< T =<…
New Magnetic Excitations in the Spin-Density-Wave of Chromium
H. Hiraka, P. Boni, Y. Endoh +3
Low-energy magnetic excitations of chromium have been reinvestigated with a single-Q crystal using neutron scattering technique. In the transverse spin-density-wave phase a new typ…
Transmission-electron-microscopy study of charge-stripe order in La(1.725)Sr(0.275)NiO(4)
Jianqi Li, Yimei Zhu, J. M. Tranquada +2
We characterize the local structure and correlations of charge stripes in La(1.725)Sr(0.275)NiO(4) using transmission-electron microscopy. We present direct evidence that the strip…
Chemical potential shift in La(1-x)Sr(x)MnO(3): Photoemission test of the phase separation scenario
J. Matsuno, A. Fujimori, Y. Takeda +1
We have studied the chemical potential shift in La(1-x)Sr(x)MnO(3) as a function of doped hole concentration by core-level x-ray photoemission. The shift is monotonous, which means…
Manipulating ionization path in a Stark map: Stringent schemes for the selective field ionization in highly excited Rb Rydberg atoms
M. Tada, Y. Kishimoto, M. Shibata +7
We have developed a quite stringent method in selectivity to ionize the low angular- momentum () states which lie below and above the adjacent manifold in highly excited Rb R…
Systematic observation of tunneling field-ionization in highly excited Rb Rydberg atoms
Y. Kishimoto, M. Tada, K. Kominato +7
Pulsed field ionization of high- (90 150) manifold states in Rb Rydberg atoms has been investigated in high slew-rate regime. Two peaks in the field ionization spe…
