Magnetic, thermal, and topographic imaging with a nanometer-scale SQUID-on-cantilever scanning probe
M. Wyss, K. Bagani, D. Jetter +7
Scanning superconducting quantum interference device (SQUID) microscopy is a magnetic imaging technique combining high-field sensitivity with nanometer-scale spatial resolution. St…
Long-range nontopological edge currents in charge-neutral graphene
Amit Aharon-Steinberg, Arthur Marguerite, David J. Perello +6
Van der Waals heterostructures display a rich variety of unique electronic properties. To identify novel transport mechanisms, nonlocal measurements have been widely used, wherein…
Sputtered MoRe SQUID-on-tip for high-field magnetic and thermal nanoimaging
Kousik Bagani, Jayanta Sarkar, Aviram Uri +4
Scanning nanoscale superconducting quantum interference devices (SQUIDs) are gaining interest as highly sensitive microscopic magnetic and thermal characterization tools of quantum…
Mapping the twist angle and unconventional Landau levels in magic angle graphene
Aviram Uri, Sameer Grover, Yuan Cao +10
The emergence of flat electronic bands and of the recently discovered strongly correlated and superconducting phases in twisted bilayer graphene crucially depends on the interlayer…
Nanoscale imaging of equilibrium quantum Hall edge currents and of the magnetic monopole response in graphene
Aviram Uri, Youngwook Kim, Kousik Bagani +9
The recently predicted topological magnetoelectric effect and the response to an electric charge that mimics an induced mirror magnetic monopole are fundamental attributes of topol…
Imaging work and dissipation in the quantum Hall state in graphene
Arthur Marguerite, John Birkbeck, Amit Aharon-Steinberg +7
Topology is a powerful recent concept asserting that quantum states could be globally protected against local perturbations. Dissipationless topologically protected states are thus…
Observation of superparamagnetism in coexistence with quantum anomalous Hall C=1 and C=0 Chern states
E. O. Lachman, M. Mogi, J. Sarkar +9
Simultaneous transport and scanning nanoSQUID-on-tip magnetic imaging studies in Cr-(Bi,Sb)Te modulation-doped films reveal the presence of superparamagnetic order within t…
Imaging resonant dissipation from individual atomic defects in graphene
Dorri Halbertal, Moshe Ben Shalom, Aviram Uri +8
Conversion of electric current into heat involves microscopic processes that operate on nanometer length-scales and release minute amounts of power. While central to our understand…
Magnetic hysteresis loop as a probe to distinguish single layer from many layer graphitic structure
K. Bagani, B. Ghosh, M. K. Ray +3
In this report we have pointed out that magnetic hysteresis loop can be used as a probe to distinguish a single layer from a many layer graphitic structure. Chemically we have synt…
