Visualizing Vortex Cluster Dynamics in the Weak Type-II Superconductor CaSb
Yusuke Iguchi, Nabhanila Nandi, Mohamed Oudah
Scanning SQUID imaging of CaSb reveals dense vortex clusters with enhanced boundary susceptibility and suppressed internal vortex motion, which features inconsistent with both…
Magnetic texture modulated superconductivity in superconductor/ferromagnet shells of semiconductor nanowires
Nabhanila Nandi, Juan Carlos Estrada Saldaña, Alexandros Vekris +11
In a one-dimensional ferromagnet-superconductor nanowire, magnetism can suppress superconductivity except where the Zeeman field is suppressed, for example domain wall superconduct…
Directional ballistic magnetotransport in the delafossite metals PdCoO and PtCoO
Michal Moravec, Graham Baker, Maja D. Bachmann +9
Studies of electronic transport in width-restricted channels of PdCoO have recently revealed a novel `directional ballistic' regime, in which ballistic propagation of electrons…
Characterization of two fast-turnaround dry dilution refrigerators for scanning probe microscopy
Mark E. Barber, Yifan Li, Jared Gibson +13
Low-temperature scanning probe microscopes (SPMs) are critical for the study of quantum materials and quantum information science. Due to the rising costs of helium, cryogen-free c…
Directional ballistic transport in the two-dimensional metal PdCoO2
Maja D. Bachmann, Aaron L. Sharpe, Arthur W. Barnard +8
In an idealized infinite crystal, the material properties are constrained by the symmetries of its unit cell. Naturally, the point-group symmetry is broken by the sample shape of a…
In situ modification of delafossite type PdCoO2 bulk single crystal for reversible hydrogen sorption and fast hydrogen evolution
Guowei Li, Seunghyun Khim, Celesta S. Chang +11
The observation of extraordinarily high conductivity in delafossite-type PdCoO2 is of great current interest, and there is some evidence that electrons behave like a fluid when flo…
Unconventional magneto-transport in ultrapure PdCoO2 and PtCoO2
Nabhanila Nandi, Thomas Scaffidi, Pallavi Kushwaha +11
We have studied magneto transport in the single-band, quasi-two-dimensional metals PdCoO2 and PtCoO2, which have extremely long mean free paths. We observer a strong temperature de…
Hydrodynamic Electron Flow and Hall Viscosity
Thomas Scaffidi, Nabhanila Nandi, Burkhard Schmidt +2
In metallic samples of small enough size and sufficiently strong momentum-conserving scattering, the viscosity of the electron gas can become the dominant process governing transpo…
Nearly-free electrons in a 5d delafossite oxide metal
Pallavi Kushwaha, Veronika Sunko, P. J. W. Moll +11
Understanding the role of electron correlations in strong spin-orbit transition-metal oxides is key to the realisation of numerous exotic phases including spin-orbit assisted Mott…
Evidence for hydrodynamic electron flow in PdCoO
Philip J. W. Moll, Pallavi Kushwaha, Nabhanila Nandi +2
Electron transport is conventionally determined by the momentum-relaxing scattering of electrons by the host solid and its excitations. The electrical resistance is set by geometri…
Crystal growth, resistivity and Hall effect of the delafossite metal PtCoO
Pallavi Kushwaha, Philip J. W. Moll, Nabhanila Nandi +1
We report single crystal growth of the delafossite oxide PtCoO, and basic transport measurements on single crystals etched to well-defined geometries using focused ion beam tec…
