 		  The Physics of Giant Magnetostriction

				Kristl Hathaway

				Washington, DC

Magnetostriction is the deformation of a body in response to a change in
its magnetization. It is a manifestation of the magnetoelastic coupling
between the classical properties of strain and elasticity, and the quantum
mechanical and relativistic phenomena of magnetism.   All magnetic
materials exhibit magnetostriction to some degree; however technologically
useful giant magnetostriction occurs only in a small number of materials
containing rare earth elements.  This talk will present a simple tutorial
on the physical origins and phenomenology of magnetostriction in crystals
and thin films, and discuss some of the issues in developing applications
of these materials.
