We study the influence of vibrational modes on the charge current and its fluctuations in atomic and molecular junctions with material-specific ab-initio techniques. Existing theoretical models are extended to include the coupling of the vibrations in the central scattering region to the surrounding electrodes to obtain a realistic description of current-induced heating. Applied to nonmagnetic systems in the first part, the techniques are generalized in the second part to treat noncollinearly magnetic nanostructures. We study the scattering between different transmission and spin channels due to vibrations and naturally take into account multiple electronic levels and vibrational modes. The externally adjustable distance between the electrodes controls precisely electronic couplings and vibrational properties, while magnetic fields provide additional external means for manipulating junctions that contain magnetic atoms or molecules.
