Interactions among magnetic dipoles induced in feeble magnetic substances under high magnetic fields

Interactions among induced magnetic dipoles were observed in the systems of feeble magnetic substances. Usually, such interactions are too small to be observed, and have been neglected so far. However, we focused on the interactions, and succeeded in observing the interactions through elaborate experiments. Furthermore, by applying this interactions to many-particle systems, some peculiar alignments were obtained. These phenomena would be of use as a control of materials structures, and bring new applications of magnetic fields in various processing. (C) 2004 Elsevier B.V. All rights reserved.
