Exact expressions for minor hysteresis loops in the random field Ising model on a Bethe lattice at zero temperature.
We obtain exact expressions for the minor hysteresis loops in the ferromagnetic random field Ising model on a Bethe lattice at zero temperature in the case when the driving field is cycled infinitely slowly.
