Abstract
High temperature superconductors with nanosized pinning centra will be prepared and studied by various methods incl. magnetic , transport, thermodynamic measurementys and characterized by AFM and STM with the atomic resolution aiming to optimize the critical parameters (as the critical current?) for practical applications? Another goal will be the feasibility studies of the systems with intrinsic Josephson junctions, for example those based on NbSe2 which are highly prospective as the Josephson arrays voltage standards
