Abstract
We study hysteresis in anti-ferromagnetic random-field Ising model at zero temperature. The external field is cycled adiabatically between - and . Two different distributions of the random-field are considered, (i) a uniform distribution of width centered at the origin, and (ii) a Gaussian distribution with average value zero and standard deviation . In each case the hysteresis loop is determined exactly in one dimension and compared with numerical simulations of the model.
