Abstract
We study here, in Ising magnets in presence of a sinusoidally varying external field, the nature of ac susceptibility arising out of the thermodynamic relaxation dynamics. The signature of the accompanying hysteresis and the dynamic phase transition are investigated in the susceptibility behaviour. These studies are made by using mean field equation of motion and the Monte Carlo method for a three dimensional Ising system. It is found that χ"(and χ') has a prominent peak (dip) as the dynamic transition phase boundary is crossed.
