Abstract

The interest in quench-disordered spin systems derives from two sources. On the one hand, there are many problems both in experimental physics and in technology where we are interested in the effect of impurities on the material properties of magnets. Impurity effects are, for instance, important for the operation of commercial magnets (coercive fields) as well as for magnetic recording devices. Frequently, nonmagnetic systems can also be represented by some appropriate spin model and again impurities may play an important role. An example is the phase separation of binary fluids in a porous medium which can be represented as a random-field Ising model. Spin-models with disorder are also useful outside condensed-matter physics. Spin-glass type models are, for instance, used as models for neural networks.
