Jl. Dejardin, NONLINEAR DIELECTRIC-RELAXATION FROM THE SMOLUCHOWSKI EQUATION FOR ROTATION IN 3 DIMENSIONS IN ALTERNATING-FIELDS, Journal of magnetism and magnetic materials, 122(1-3), 1993, pp. 187-192
Analytic expressions for the nonlinear response of the dielectric rela
xation are established. Three harmonic components are found arising fr
om the application of a weak alternating field superimposed on a stron
g direct field. Dispersion plots and Cole-Cole diagrams illustrate the
deviation from the classical Debye theory and give interesting inform
ation on molecular parameters.
