Abstract
The complex susceptibility or the dynamic susceptibility (Ï(Ï)=Ïâ²(Ï)âiÏâ³(Ï)) for a spin-1 Ising system with bilinear and biquadratic interactions is obtained on the basis of Onsager theory of irreversible processes. If the logarithm of the susceptibilities is plotted as a function of the logarithm of frequency, then the real part (Ïâ²) displays a sequence of plateau regions and the imaginary part (Ïâ³) has a sequence of maxima in the ordered or ferromagnetic phase. On the other hand, only one plateau region in Ïâ² and one maximum in Ïâ³ is observed in the disordered or paramagnetic phase. Argand or Cole-Cole plots (Ïâ³âÏâ²) for a selection of temperatures are also shown, and a sequence of semicircles is illustrated in the ordered phase and only one semicircle for the disordered phase in these plots.
