Plasticity and stress engineering of cuprate superconductors

ORAL

Abstract

Ceramic materials, including the cuprate high-temperature superconductors, are generally thought to be brittle at low temperatures due to their rigid ionic and covalent bonding. We present here the surprising discovery of room-temperature plasticity in the cuprates, observed with compressive stress perpendicular to the copper-oxygen planes. We further show that the electronic properties, in particular superconductivity, can be manipulated via plastic deformation. We discuss the origin of these effects and correlate them with structural changes as investigated by neutron and X-ray diffuse scattering measurements.
