Ebook: Amorphous Magnetism: Proceedings of the International Symposium on Amorphous Magnetism, August 17–18, 1972, Detroit, Michigan

The title of amorphous magnetism was conceived to en­ compass the study of the magnetic properties of dilute ran­ dom substitutional alloys, amorphous metallic alloys, amor­ phous magnetic semiconductors and the conventional glasses, including cha1cogenide, organic and inorganic glasses. These materials have heretofore been considered to be quite different because of the differences in their atomic struc­ tures. However, when the magnetic behavior of these mater­ ials is carefully examined it becomes clear that these materials exhibit certain similarities. For the first time at the International Symposium on Amorphous Magnetism held at Wayne State University in Detroit, Michigan on August 17 and 18, 1972, scientists working in these areas were assembled to examine the similarities of these systems. This volume contains a summary of the 9 invited talks, 23 delivered, contributed papers and an additional 12 contri­ buted papers whcih were not presented because of insuffic­ ient time in the program. This volume presents for the first time a collection of the most current theoretical and experimental studies in the area of amorphous magnetism. We wish to thank the authors of these papers for their outstanding cooperation in preparing their manuscripts and for editing our transcriptions from tape recordings of the discussions which followed their presentations. In addition, we wish to thank the participants at this conference whose enthusiasm and interest made the conference so successful.
