Abstract
We show that the random-field Ising model may be tuned to obtain two d istinct scenarios of phase diagram topology. Explicit evidence for thi s is presented in a numerically exact analysis in three dimensions and on a Bethe lattice, which allows us to investigate the effects of tem perature, coordination number, and asymmetry in the field distribution .
