Yw. Yu et Jw. Harrell, FMR DETERMINATION OF DAMPING CONSTANTS IN MAGNETIC TAPES, Journal of magnetism and magnetic materials, 155(1-3), 1996, pp. 126-128
FMR spectra have been measured in a series of CrO2 tapes, three metal
evaporated tapes and a highly-viscous gamma=Fe2O3 tape in order to ext
ract the damping constants. For CrO2 the damping constant was approxim
ately independent of orientation and coercivity. A strong correlation
has been found between the damping constant of these and previously me
asured tapes and switching speed measurements made by other investigat
ors.
