Terahertz charge and spin transport in metallic ferromagnets: The role of crystalline and magnetic order

We study the charge and spin dependent scattering in a set of CoFeB thin films whose crystalline order is systematically enhanced and controlled by annealing at increasingly higher temperatures. Terahertz conductivity measurements reveal that charge transport closely follows the development of the c...
