Spin Glass Theory

  • Giorgio Parisi
Part of the NATO ASI Series book series (volume 167)


A spin glass is a disordered magnet: in a typical example 50% of the bonds (randomly chosen) between two spins are ferromagnetic while the others are antiferromagnetic. From the experimental point of view(1) spin glasses are characterized by the presence of a low temperature phase in which the relaxation time toward equilibrium is very large (as in real glasses). The magnetic susceptibility in the presence of a time dependent magnetic field depends on the frequency also in the region of a few Hertz.
