Single Vortex Pinning and Penetration Depth in Superconducting NdFeAsOF
Jessie T. Zhang, Jeehoon Kim, Magdalena Huefner +6
We use a magnetic force microscope (MFM) to investigate single vortex pinning and penetration depth in NdFeAsOF, one of the highest- iron-based superconductors. In…
Spatial mapping and manipulation of two tunnel-coupled quantum dots
Magdalena Huefner, Bruno Kueng, Stephan Schnez +4
The metallic tip of a scanning force microscope operated at 300 mK is used to locally induce a potential in a fully controllable double quantum dot defined via local anodic oxidati…
Imaging Localized States in Graphene Nanostructures
S. Schnez, J. Güttinger, M. Huefner +3
Probing techniques with spatial resolution have the potential to lead to a better understanding of the microscopic physical processes and to novel routes for manipulating nanostruc…
Aharonov-Bohm effect in a side-gated graphene ring
Magdalena Huefner, Françoise Molitor, Arnhild Jacobsen +4
We investigate the magnetoresistance of a side-gated ring structure etched out of single-layer graphene. We observe Aharonov-Bohm oscillations with about 5% visibility. We are able…
