Description
The core-free magnetic configuration of ferromagnetic nanotubes leads to a controllable and fast reversal process and makes them promising candidates for high-density data storage, magnetic sensors, and logic device elements. We explore the magnetic configurations of different individual ferromagnetic nanotubes that we deposited on semiconductor nanowires of GaAs. Nanotubes prepared from permalloy or CeFeB have diameters ranging from 130 to 200 nm and a length in the range of 5 - 20 micrometers. We perform measurements on the magnetoresistance and anomalous Nernst effect. The research is funded by the DFG via GR1640/5-2.
