ABSTRACT:
The invention herein is directed towards a material exhibiting superconductivity characteristics which includes a laser processed region of a metal oxide crystal. The material has a transition temperature greater than a transition temperature of the metal oxide crystal, preferably greater than 140K. The transition temperature of the material may be considered greater than the transition temperature of the metal oxide crystal if the material has a transition temperature and the metal oxide crystal has no transition temperature. The present invention is also directed to a material which includes a laser processed strontium ruthenate crystal wherein the material has a greater oxygen content than the starting strontium ruthenate crystal. The present invention is also directed towards a method for manufacturing a material exhibiting superconductivity characteristics that includes providing a metal oxide crystal and laser ablating the metal oxide crystal and a material made by this process.
