Resistance Oscillations and Electron Localization in Cylindrical Mg Films

Abstract
Longitudinal magnetoresistance measurements of hollow Mg cylinders between 1.5 and 10 K are reported and analyzed within the framework of weak electron-localization theories. The observed resistance oscillations decrease with increasing cylinder diameter and temperature, in excellent agreement with the theory of Altshuler et al. The phase-breaking and spin-orbit-interaction times are comparable to the values obtained in plane Mg films.
