Abstract: The response of a complex system to a slowly and smoothly varying force sometimes becomes jerky eg. earthquakes, avalanches, Barkhausen noise etc. Such behaviour is studied using a minimal model: the RFIM. The general criteria for the occurrence of nonequilibrium critical behaviour on Bethe lattices and studies on some periodic lattices in the framework of RFIM shall be discussed.
