High magnetic field evolution of the in-plane angular magnetoresistance of electron-doped Sr1-xLaxCuO2 in the normal state
V. P. Jovanović, H. Raffy, Z. Z. Li +2
We studied the in-plane angular magnetoresistance (AMR), in the normal state, of underdoped superconducting Sr1-xLaxCuO2 , which has the simplest crystal structure among cuprates.…
Transport properties of very overdoped nonsuperconducting Bi2Sr2CuO6+d thin films
H. Raffy, Z. Z. Li, P. Auban-Senzier
The transport properties, resistance, Hall effect, and low T magnetoresistance for very oxygen overdoped nonsuperconducting Bi2Sr2CuO6+d (Bi2201) thin films are reported. From 20 t…
Universal -linear resistivity and Planckian limit in overdoped cuprates
A. Legros, S. Benhabib, W. Tabis +13
The perfectly linear temperature dependence of the electrical resistivity observed as 0 in a variety of metals close to a quantum critical point is a major puzzle o…
Destroying coherence in high temperature superconductors with current flow
A. Kaminski, S. Rosenkranz, M. R. Norman +4
The loss of single-particle coherence going from the superconducting state to the normal state in underdoped cuprates is a dramatic effect that has yet to be understood. Here, we a…
Quasiparticles dynamics in high-temperature superconductors far from equilibrium: an indication of pairing amplitude without phase coherence
C. Piovera, Z. Zhang, M. d'Astuto +6
We perform time resolved photoelectron spectroscopy measurements of optimally doped $\tn{Bi}_2\tn{Sr}_2\tn{CaCu}_2\tn{O}_{8+δ}$ (Bi-2212) and $\tn{Bi}_2\tn{Sr}_{2-x}\tn{La}_{x}\tn{…
Zero-bias anomalies on SrLaCuO thin films
L. Fruchter, F. Bouquet, Z. Z. Li
High-impedance contacts made on the surface of SrLaCuO superconducting thin films systematically display a zero-bias anomaly. We consider two-level systems (T…
Point-Contact spectroscopy on electron-doped SrLaCuO thin films
L. Fruchter, F. Bouquet, Z. Z. Li
We report on the spectra of point-contacts made on SrLaCuO thin films. Besides a clear evidence for the superconducting gap, we discuss the origin of specific…
Electric--field effect on electron-doped infinite-layer SrLaCuO thin films
L. Fruchter, F. Bouquet, Z. Z. Li
We have used the electric--field effect to modulate the resistivity of the surface of underdoped SrLaCuO thin films, allowing opposite modifications of th…
Anisotropy of the in-plane angular magnetoresistance of electron-doed Sr1-xLaxCuO2 thin films
V. P. Jovanović, L. Fruchter, Z. Z. Li +1
Signatures of antiferromagnetism (AF) in the underdoped Ln2-xCexCuO4 (Ln = Nd, Pr,...) family are observed even for doping levels for which superconductivity exists. We have looked…
Penetration depth of electron-doped-infinite-layer SrLaCuO thin films
L. Fruchter, V. Jovanovic, H. Raffy +3
The in-plane penetration depth of SrLaCuO thin films at various doping obtained from oxygen reduction has been measured, using AC susceptibility measureme…

U. Chatterjee, M. Shi, D. Ai +15
We use angle resolved photoemission spectroscopy to probe the electronic excitations of the non-superconducting state that exists between the antiferromagnetic Mott insulator at ze…
Resistance noise in Bi_2Sr_2CaCu_2O
L. Fruchter, H. Raffy, Z. Z. Li
The resistance noise in a Bi_2Sr_2CaCu_2O thin film is found to increase strongly in the underdoped regime. While the increase of the raw resistance noise with decreasing t…
Anomalous dispersion in the autocorrelation of ARPES data of BiSrCaCuO

The ab-plane reflectance of Bi2Sr2CaCu2O(8+d) thin films was measured in the 30-25000 cm^(-1) range for one underdoped (Tc = 70 K), and one overdoped sample (Tc = 63 K) as a functi…
Electronic Spectra and Their Relation to the (pi,pi) Collective Mode in High-Tc Superconductors
J. C. Campuzano, H. Ding, M. R. Norman +15
Photoemission spectra of Bi2Sr2CaCu2O8 reveal that the high energy feature near (pi,0), the "hump", scales with the superconducting gap and persists above Tc in the pseudogap phase…
