PREFACE TO THE PROCEEDINGS

       The European Conference "Physics of Magnetism 93: Strongly Correlated Electron Systems", was held on June 21-24, 1993 at the Science Center of the Polish Academy of Sciences in Poznań. The Conference was organized jointly by the Institute of Physics of the Adam Mickiewicz University in Poznań and the Institute of Molecular Physics of the Polish Academy of Sciences in Poznań. It was continuation of the previous conferences which were held every 3 years in Poznań since 1975, and which have gained more and more an international character over the past few years.

       Conference was meant to be an international forum for presentation and discussion of novel scientific ideas, experimental results and new magnetic materials, with special emphasis on the physics of strongly correlated electron systems. The objective of the Conference was to bring together scientists and technologiest from the Western, Central and Eastern countries, involved in research and application of magnetic materials and high temperature superconductors.

       The program of the Conference consisted of 17 invited talks, presented by distinguished physicist from Europe and USA. There were 180 participants from Poland and 40 from other ten European countries and USA. More than 180 contributions were presented in a poster or oral form.

       All the invited talks, ptrovided by the Authors, and selected contributed papers (after being refereed) are published in this special issue ^(*) of the Acta Physica Polonica A.

       The major sponsors of the Conference, i.e. the Committee for Scientific Research, the Ministry of National Education and the Committee of Physics of the Polish Academy of Sciences, are kindly acknowledged.
