Abstract

By means of ultrahigh-resolution dilatometry we have studied the linear expansion coefficients at the superconducting transition for directions along and perpendicular to the superconducting layers. A pronounced discontinuity was found along the interlayer direction which corresponds to an extraordinary large uniaxial-pressure dependence of dTc/dpa* = -4.8K/kbar. This indicats a most sensitive coupling between superconductivity and interlayer spacing in this layered superconductor.
