Abstract
We study critical hysteresis in the random-field Ising model on a two-dimensional periodic lattice with a variable coordination number in the range . We find that the model supports critical behavior in the range , but the critical exponents are independent of . The result is discussed in the context of the universality of nonequilibrium critical phenomena and extant results in the field.
