Effect of Single Particle Hopping and out of Plane Magnetic Impurity on Coupled Planar Superconductors
Manas Sardar, Debanand Sa
Abstract
It is shown that the single particle band motion along the c axis is harmful for superconductivity. Variation of Tc with c axis hopping parameter is shown for both the conventional planar superconductors and for interlayer pair tunneling mechanism of Wheatley Hsu and Anderson(WHA).Effect of out of plane magnetic impurity substitution is shown to suppres Tc more for conventional superconductors whereas there is very sharp decrease of Tc in the WHA mechanism at larger concentrations.
