Nonlocal vortex motion in mesoscopic amorphous Nb0.7Ge0.3 structures

Autor: Helzel, A., Kokanovic, I., Babic, D., Litvin, L. V., Rohlfing, F., Otto, F., Surgers, C., Strunk, C.

We study nonlocal vortex transport in mesoscopic amorphous Nb0.7Ge0.3 samples. A dc current I is passed through a wire connected via a perpendicular channel, of a length L= 2-5 um, with a pair of voltage probes where a nonlocal response Vnl ~ I is me

Interface-induced enhancement of the anomalous Nernst effect in ferromagnetic Mn$_5$Ge$_3$C$_{0.8}$ films

Autor: Srichandan, S., Deng, S., Fischer, I. A., Sürgers, C.

The anomalous Nernst effect of thin bilayers comprising a thin normal metal film and a ferromagnetic Mn$_5$Ge$_3$C$_{0.8}$ film has been investigated. Epitaxial c-axis grown Mn$_5$Ge$_3$C$_{0.8}$ films have been obtained by e-beam evaporation as well
