"In this thesis the results of the first systematic application of magnetic field microscopy using ultracold atoms are presented. The properties of charge transport in thin film polycrystalline gold wires are examined in a previously not accessible regime. The field sensor based on ultracold atoms facilitates a microscopic mapping of directional fluctuations in the local current direction at an angle resolution of 1E-5 rad over length scales between 10E-6 m and 600E-6 m. The measurements show an orientational preference in the directional fluctuations which is explained within an ohmic defect model. The absolute magnitude of the fluctuations (rms angle fluctuations between 60E-6 rad and 160E-6 rad) are interpreted by different contributions of surface and bulk defects. The methods that are necessary for the implementation and interpretation of a quantitative magnetic field microscopy using ultracold atoms are described thoroughly."^^ . "2007" . . . . . . . .
