Magnetoresistance of films and strips with the diffuse surface scattering

Technical Report:

Abstract

Magnetoresistance of films in a parallel magnetic field and strips in a perpendicular field is considered. The temperature and magnetic field dependencies of magnetoconductance depend on the time evolution of the correlator of phases. This correlator has different behavior as the function of time: the ergodic behavior at small magnetic fields is changed on the nonergodic one at large magnetic fields in spite of the diffusion electron motion due to a diffuse scattering on boundaries. This leads to unusual temperature and magnetic field dependencies of magnetoresistance. The ergodic hypothesis is not applicable to mesoscopical fluctuations at such a large quasiclassical field. (author). 6 refs, 5 figs.
