Ordered Defects: A Roadmap towards room temperature Superconductivity and Magnetic Order
Defects in the atomic lattice of solids are sometimes desired. For example, atomic vacancies, single ones or more elaborated defective structures, can generate localized magnetic moments in a non magnetic crystalline lattice. Increasing their density to a few percent magnetic order can appear. Furthermore, certain two dimensional interfaces can give rise to localized superconductivity with a broad range of critical temperatures. Old and new experimental facts emphasize the need to join efforts to start using systematically "ordered defects" in solids to achieve room temperature superconductivity and magnetic order.
