The first-order reversal curve (FORC) method is applied to thetwo-dimensional kinetic Ising model. For the system size and magnetic fieldchosen, the system reverses by the homogeneous nucleation and growth of manydroplets. This makes the dynamics of reversal nearly deterministic, in contrastto the strongly disordered systems previously studied by the FORC method.Consequently, the FORC diagrams appear different from those obtained inprevious studies. The Kolmogorov-Johnson-Mehl-Avrami (KJMA) theory of phasetransformation by nucleation and growth is applied to the system. Reasonableagreement with the Monte Carlo simulations is found, and the FORC methodsuggests how the KJMA theory could be extended.Comment: 3 pages, 2 figures, presented at 2004 MMM meeting, to appear in  conference proceedings in J. Appl. Phys. (May 2005); rephrased several  section
