Physics of Magnetocaloric and Magnetostrictive Materials

The magnetocaloric effect ("MCE") and the concept of magnetic cooling at room temperature has received renewed interest in recent years due to the discovery of new materials. This short workshop will provide an introduction to the field of magnetocaloric materials. Magnetocaloric materials often possess other interesting properties (magnetoresistance, magnetostriction) associated with the magnetic transition at which the magnetocaloric effect is maximal. For this workshop, topics to be covered include: the magnetocaloric effect, metamagnetism, non-collinear magnetic order and magnetostriction. Many promising magnetocaloric materials show a strong magnetoelastic interaction. It is therefore natural to confront new scientific results in the field of magnetostriction with those on the magnetocaloric effect.

Workshop Aims

The first MMMR workshop was held in Cambridge in 2006 and was focused on magnetocaloric materials. This workshop in Vienna aims to bring together scientists specialized in magnetocaloric materials with those doing research in magnetostriction in order to stimulate new developments in both fields of research.

Abstract Deadline

If you wish to present, the (extended) deadline for submitting abstracts is June 7^th 2007.

The maximum number of participants is restricted to 40.

Abstracts will be considered on a first come first serve basis.
