Abstract

The magnetic behavior of giant magnetostrictive TbFe/FeCo multilayers show that individual layers of as-deposited multilayers in their demagnetized state are single domain due to stray-field coupling between adjacent layers. Such multilayers do not show a collective behavior during magnetization reversal. In contrast, stress-free films obtained by annealing at 543 K for 1 h subdivide themselves into multiple domains to lower their overall energy, and show a collective magnetization behavior. An interesting observation is the dynamic formation and collapse of magnetoelastically induced domains in TbFe layers in annealed multilayers during reversal.
