Observation of square flux-line lattice in the unconventional superconductor Sr(sub2)RuO(sub4)

Article Abstract:

Superconductivity is of considerable scientific and practice interest and to gain further information about the properties of the superconductor, the intensity of the flux-line lattice (Fll) signal must be understood, or the magnitude of the Fourier components. A small-angle neutron-scattering measurement of magnetic flux lines in the Sr(sub2)RuO(sub4) perovskite superconductor was taken. Magnetic flux lines were found to form a square lattice over broad field and temperature fields.

Electron pockets in the Fermi surface of hole-doped high-[T.sub.c] superconductors

Article Abstract:

A negative Hall resistance observed in the magnetic-field-induced normal state of Y[Ba.sub.2][Cu.sub.3][O.sub.y] and Y[Ba.sub.2][Cu.sub.4][O.sub.8], which revealed electron-like pockets is reported. The electron pocket formation is attributed to reconstruction of the Fermi surface caused by the onset of a density-wave phase or due to high-transition-temperature [T.sub.c] superconductors.

A coherent three-dimensional fermi surface in a high-transition-temperature superconductor

Article Abstract:

The high-transition-temperature copper oxide superconductors have unusual highly two-dimensional properties above the superconducting transition. All conventional metals are known to possess a three-dimensional fermi surface, which is the locus in reciprocal space of the long-lived electronic excitations that govern their electronic properties at low temperatures.
