Abstract
The magnetic damping in pure iron has been studied over the temperature range 140–300 K using a single-crystal slab l5 μm thick. The results at room temperature are consistent with the accepted value of the damping parameter for iron of G=0.7×108 Hz. The damping increases as the temperature is reduced and reaches a value of approximately 1.4×108 Hz at 140 K.
