Dynamic cantilever magnetometry of individual CoFeB nanotubes
B. Gross, D. P. Weber, D. Rüffer +5
We investigate single CoFeB nanotubes with hexagonal cross-section using dynamic cantilever magnetometry (DCM). We develop both an analytical model based on the Stoner-Wohlfarth ap…
Magnetization reversal of an individual exchange biased permalloy nanotube
A. Buchter, R. Wölbing, M. Wyss +14
We investigate the magnetization reversal mechanism in an individual permalloy (Py) nanotube (NT) using a hybrid magnetometer consisting of a nanometer-scale SQUID (nanoSQUID) and…
Nonlinear motion and mechanical mixing in as-grown GaAs nanowires
F. R. Braakman, D. Cadeddu, G. Tütüncüoglu +4
We report nonlinear behavior in the motion of driven nanowire cantilevers. The nonlinearity can be described by the Duffing equation and is used to demonstrate mechanical mixing of…
Untangling the role of oxide in Ga-assisted growth of GaAs nanowires on Si substrates
F. Matteini, G. Tutuncuoglu, D. Rüffer +2
The influence of the oxide in Ga-assisted growth of GaAs nanowires on Si substrates is investigated. Three different types of oxides with different structure and chemistry are cons…
Reversal mechanism of an individual Ni nanotube simultaneously studied by torque and SQUID magnetometry
A. Buchter, J. Nagel, D. Rüffer +15
Using an optimally coupled nanometer-scale superconducting quantum interference device, we measure the magnetic flux originating from an individual ferromagnetic Ni nanotube attach…
Electrical transport in C-doped GaAs nanowires: surface effects
Alberto Casadei, Jil Schwender, Eleonora Russo-Averchi +7
The resistivity and the mobility of Carbon doped GaAs nanowires have been studied for different doping concentrations. Surface effects have been evaluated by comparing upassivated…
Experimental observation of an enhanced anisotropic magnetoresistance in non-local configuration
Daniel Rüffer, Franz D. Czeschka, Rudolf Gross +1
We compare non-local magnetoresistance measurements in multi-terminal Ni nanostructures with corresponding local experiments. In both configurations, the measured voltages show the…
