| Zusammenfassung | The interplay between charge, spin, and heat currents in magnetic nano systems subjected to a temperature gradient has led to a variety of novel effects and promising applications studied in the fast-growing field of spincaloritronics. In this context, the magneto-Seebeck effects of magnetic tunnel junctions, superlattices and nanowires have been studied which established a new line of research. Here we explore the magnetothermoelectrical properties of one more fundamental system: the magnetic domain wall. The domain walls are generated in L-shaped permalloy nanowires with a notch. In thermal gradients of the order of few Kelvin per micrometer along the long wire axis, we find a clear magneto-Seebeck signature of a single domain wall. The results can be explained by the magnetization-dependent Seebeck coefficient of permalloy in combination with the spatially localized change of spin configuration due to the presence of a domain wall. |
