As the annealing temperature increases, the damping constant is found to be slightly decreased first and then, rapidly increased. The minimum damping constant is, thus, obtained with a 300 A degrees C-annealed Ta/CoFeB/Ta film while the samples with Ru and Pd layers exhibit their minimum at 200 A degrees C. The coercive field also exhibits a behavior similar to the damping constant; thus, an empirical correlation between them is proposed.
