High-resolution neutron-scattering measurements of the random-field Ising phase-transition behavior in Mn0.75{Zn}0.25F₂ are reported. An abrupt, apparently discontinuous, transition at TN(H) from history-independent to history-dependent behavior occurs; below TN(H) all states with length scales between the field-cooled value and infinity are stable for indefinite lengths of times; logarithmic decay of the domain size in time may be ruled out. No existing theory accounts for this transition behavior.
