Аннотация
The paper considers the logarithmic addition to electrical resistance, which determines the increase in the resistance of thin bismuth films as the temperature is lowered below Tmin≃5 — 10 °K, as well as their anomalous magnetoresistance. These effects are considered in conjunction with theoretical calculations of the mechanisms of electron localization and electron-electron interaction with elastic electron scattering.
