| Research Abstract |
We investigated ultrafast demagnetization for epitaxial Heusler films using an all-optical pump-probe technique. Values of demagnetizationτM increased with the laser power P for Mn-Ga alloys and perpendicular magnetized Co-alloys, this is consistent with microscopic theory. On the other hand,τM decreased with P for Co_2MnSi Heusler alloys on Ag and Cr buffer layers.
