Magnetic ordering and spin waves in
S. P. Bayrakci, I. Mirebeau, P. Bourges +6
NaCoO, the parent compound of the recently synthesized superconductor NaCoO:HO, exhibits bulk antiferromagnetic order below K for 0.75 …
Two-Dimensional Geometry of Spin Excitations in the High Temperature Superconductor YBa2Cu3O6+x
V. Hinkov, S. Pailhes, P. Bourges +7
The fundamental building block of the copper oxide superconductors is a Cu4O4 square plaquette. In most of these materials, the plaquettes are slightly distorted and form a rectang…
In-Plane Spectral Weight Shift of Charge Carriers in
A. V. Boris, N. N. Kovaleva, O. V. Dolgov +4
The temperature dependent redistribution of the spectral weight of the plane derived conduction band of the high temperature superconductor (T_c = 92.7 K…
Charge ordering and magneto-polarons in NaCoO
C. Bernhard, A. V. Boris, N. N. Kovaleva +6
Using spectral ellipsometry, we have measured the dielectric function of a NaCoO crystal that exhibits bulk antiferromagnetism with T=19.8 K. We identify two…
Intrinsic Josephson Effects in the Magnetic Superconductor RuSr2GdCu2O8
T. Nachtrab, D. Koelle, R. Kleiner +2
We have measured interlayer current transport in small sized RuSr2GdCu2O8 single crystals. We find a clear intrinsic Josephson effect showing that the material acts as a natural su…
The crystal growth and characterization of NaxCoO2 and NaxCoO2yH2O
D. P. Chen, H. C. Chen, A. Maljuk +4
A systematic study of NaxCoO2 (x=0.50 - 0.90) and NaxCoO2 yH(D)2O (x=0.26 - 0.42, y=1.3) has been performed to determine phase stability and the effect of hydration on the structur…
