This is a combined volume of the Proceedings for the Workshop on 'Mechanisms of High Tc Superconductivity' (20 June –29 July) and the Adriatico Research Conference (26 - 29 July) on high temperature superconductivity. It aims to bring together a critical overview of the experimental situation and an in-depth discussion of the various theoretical models proposed to explain the mechanisms for high temperature superconductivity by experts actively involved in high Tc research.

This proceedings contains the works of both experimental and theoretical aspects of high temperature superconductivity with special emphasis on the results obtained by nuclear methods (e.g. neutron scattering, μSR, positron annihilation and Mössbauer spectroscopy).

This Conference is designed to cover the entire field of current-carrying properties of superconductors, either metallic alloys or the new high-Tc metallic oxides. Related topics will be treated as well as the large scale applications. Topics covered include magnetization and flux behaviour, current transport and critical currents, Josephson junctions and proximity effect, microwave absorption and rf surface resistance, thermal conductivity and specific heat, Hall effect and thermoelectric power, thermal fluctuations and paraconductivity, applications of high-Tc materials.

The subject of the School is on the theory and phenomenology of 'classical' superconductivity. However, the selection and treatment of the different topics is done in the perspective of the new, 'high Tc'' materials, in order to clarify what is already contained in the BCS frame, and what is not.

This Symposium aims to present and discuss recent advances on the experimental, theoretical and applications aspects of superconductivity. It provides a forum for scientists working on superconductivity to interact and solve mutual problems. All invited papers are by leading experts in the field.

This volume covers up-to-date ideas associated with the studies of high Tc superconductivity. Diverse theoretical points of view on the nature of this phenomenon are presented in the book. Experimental works discuss the results obtained in the studies of Bi and Tl superconductivity compounds as well as the thorough investigation of the different properties of 123 (YBaCu) compounds. Several articles are devoted to SQUIDs functioning at nitrogen temperatures and their application in research work.
