Screw dislocations: The key to high critical currents in YBa2Cu3O7?

Authors


Abstract

Research News: Defects in high-Tc superconductors recently observed with the aid of scanning tunneling microscopy could hold the key to increased critical current densities, a crucial requirement for power applications. The observation, by teams from the Los Alamos National Laboratory, and IBM Zurich, and origin of the defects (see Figure) are discussed.
