Triplanar Model for the Gap and Penetration Depth in YBCO
C. O'Donovan, J. P. Carbotte
YBaCuO_7 is a trilayer material with a unit cell consisting of a CuO_2 bilayer with a CuO plane of chains in between. Starting with a model of isolated planes coupled through a tra…
c-axis Josephson Tunnelling in Twinned and Untwinned YBCO-Pb Junctions
C. O'Donovan, M. D. Lumsden, B. D. Gaulin +1
Within a microscopic two band model of planes and chains with a pairing potential in the planes and off diagonal pairing between planes and chains we find that the chains make the…
a-b Plane Anisotropy in YBCO
W. Atkinson, J. P. Carbotte, C. O'Donovan
The zero temperature in plane penetration depth in an untwinned single crystal of optimally doped YBa_2Cu_3O_6.93 is highly anisotropic. This fact has been interpreted as evidence…
Effects of Interlayer Interaction on the Superconducting State in YBCO
C. O'Donovan, J. P. Carbotte
For a two layer system in a weak coupling BCS formalism any interlayer interaction, regardless of its sign, enhances the critical temperature. The sign has an effect upon the relat…
S and D Wave Mixing in High Superconductors
C. O'Donovan, J. C. Carbotte
For a tight binding model with nearest neighbour attraction and a small orthorhombic distortion, we find a phase diagram for the gap at zero temperature which includes three distin…
