Pc. Fannin et al., ON THE GENERATION OF COMPLEX SUSCEPTIBILITY DATA THROUGH THE USE OF THE HILBERT TRANSFORM, Journal of physics. D, Applied physics, 26(11), 1993, pp. 2006-2009
It is shown that, by the use of the Hilbert transform, it is possible
to obtain values of the imaginary component, chi''(omega), of the AC m
agnetic susceptibility of a colloidal suspension of single-domain magn
etic particles, from experimental measurements of the real component,
chi'(omega).
