FMR linewidth and the crystallization processes in Co-based amorphous microwires

► This work presents FMR linewidth measurements on Co-based amorphous microwires. ► Crystallization process can be followed by the evaluation of the damping terms. ► Three ranges of annealing temperatures can be distinguished in terms of spin dynamics. ► The temperature ranges are: below the TCurie, above the TCrystal and between both.
