The Collective Coordinate Method and Bloch Wall Motion the so-called “collective coordinate method”. It is meant to be a tutorial and very informal approach to the subject. Although the emphasis will be on magnetic systems the method can also be applied to many other non-linear one dimensional field theoretical models.

Evidence for Quantum Tunneling of the Magnetization in Mn12A Co present the hysteresis properties of Mn.Ac measured at low temperatures. The properties differ from those of ferromagnetic materials. They are not due to arrangements of magnetic domains, but to a self-induced magnetization reversal, the socalled ..

Linear Response and Thermal Equilibrium Noise of Magnetic Materials at Low Temperature: Logarithmic ilibrium. Several different temperature dependencies have been found including temperature independent viscosities and crossover to temperature dependent behaviours. We discuss these results in connection with the problem of the quantum tunnelling of the magnetization.
