Pc. Fannin et al., ON THE USE OF FREQUENCY-DOMAIN MEASUREMENTS TO INVESTIGATE TIME-DOMAIN MAGNETIZATION DECAY IN A FERROFLUID, Journal of physics. D, Applied physics, 27(2), 1994, pp. 194-197
A technique that enables one to investigate the magnetization decay of
a ferrofluid by means of processed complex susceptibility data is pre
sented. The presence of a particle size distribution, and hence a dist
ribution of relaxation times, is accounted for by means of the Frohlic
h distribution function.
