The hierarchy of multiple many-body interaction scales in high-temperature superconductors
W. Meevasana, X. J. Zhou, S. Sahrakorpi +28
To date, angle-resolved photoemission spectroscopy has been successful in identifying energy scales of the many-body interactions in correlated materials, focused on binding energi…
Magnetization, Nernst effect and vorticity in the cuprates
Lu Li, Yayu Wang, M. J. Naughton +4
Nernst and magnetization experiments reveal the existence of a large region of the cuprate phase diagram above the curve in which vorticity and weak diamagnetism exist withou…
Low-Energy Electronic Structure of the High-Tc Cuprates La2-xSrxCuO4 Studied by Angle-resolved Photoemission Spectroscopy
T. Yoshida, X. J. Zhou, D. H. Lu +8
We have performed a systematic angle-resolved photoemission spectroscopy (ARPES) study of the high-Tc cuprates La2-xSrxCuO4, ranging from the underdoped insulator to the supercondu…
Depairing field, onset temperature and the nature of the transition in cuprates
Lu Li, Yayu Wang, J. G. Checkelsky +5
The depairing (upper critical) field in hole-doped cuprates has been inferred from magnetization curves - measured by torque magnetometry in fields up to 45 T. W…
Strong charge fluctuations manifested in the high-temperature Hall coefficient of high-T_c cuprates
S. Ono, Seiki Komiya, Yoichi Ando
By measuring the Hall coefficient R_H up to 1000 K in La_2CuO_4, Pr_{1.3}La_{0.7}CuO_4, and La_{2-x}Sr_xCuO_4 (LSCO), we found that the temperature (T) dependence of R_H in LSCO fo…
Evolution of the low energy spin dynamics in electron-doped high-transition temperature superconductor Pr0.88LaCe0.12CuO4-d
Stephen D. Wilson, Shiliang Li, Pengcheng Dai +7
We use inelastic neutron scattering to explore the evolution of the low energy spin dynamics in the electron-doped cuprate Pr0.88LaCe0.12CuO4-d (PLCCO) as the system is tuned from…
Doping n-type carriers by La-substitution for Ba in YBa_2Cu_3O_y system
Kouji Segawa, Yoichi Ando
Thus far, there is no cuprate system where both n-type and p-type charge carriers can be doped without changing the crystallographic structure. For studying the electron-hole symme…
On the production of flat electron bunches for laser wake field acceleration
M. Kando, Y. Fukuda, H. Kotaki +8
We suggest a novel method for injection of electrons into the acceleration phase of particle accelerators, producing low emittance beams appropriate even for the demanding high ene…
Negative Hall coefficients of heavily overdoped La2-xSrxCuO4
I. Tsukada, S. Ono
The Hall coefficient (R_H) is investigated along the in-plane direction for carefully prepared La_2-x_Sr_x_CuO_4_ thin films from x=0.08 to x=0.40. It is found that R_H becomes alm…
High Energy Spin Excitations in Electron-Doped Superconducting PrLaCeCuO with K
Stephen D. Wilson, Shiliang Li, H. Woo +5
We use high-resolution inelastic neutron scattering to study the low-temperature magnetic excitations of electron-doped superconducting PrLaCeCuO ($T_c=21…
Origin of the large thermoelectric power in oxygen-variable RBaCo_{2}O_{5+x} (R=Gd, Nd)
A. A. Taskin, A. N. Lavrov, Yoichi Ando
Thermoelectric properties of GdBaCo_{2}O_{5+x} and NdBaCo_{2}O_{5+x} single crystals have been studied upon continuous doping of CoO_2 planes with either electrons or holes. The th…
Field dependence of the magnetic spectrum in anisotropic and Dzyaloshinskii-Moriya antiferromagnets: II. Raman spectroscopy
L. Benfatto, M. B. Silva Neto, A. Gozar +5
We compare the theoretical predictions of the previous article [L. Benfatto and M. B. Silva Neto, cond-mat/0602419], with Raman spectroscopy experiments in Sr(2)CuO(2)Cl(2) and unt…
Crystal structure and high-field magnetism of La2CuO4
M. Reehuis, C. Ulrich, K. Prokes +6
Neutron diffraction was used to determine the crystal structure and magnetic ordering pattern of a La2CuO4 single crystal, with and without applied magnetic field. A previously unr…
Critical microwave-conductivity fluctuations across the phase diagram of superconducting LaSrCuO thin films
Haruhisa Kitano, Takeyoshi Ohashi, Atsutaka Maeda +1
We report a systematic study of the dynamic microwave conductivity near for LaSrCuO (LSCO) thin films with =0.07 to 0.16. The strong frequency dependence o…
