Realization of Artificial Ice Systems for Magnetic Vortices in a Superconducting MoGe Thin-film with Patterned Nanostructures
M. L. Latimer, G. R. Berdiyorov, Z. L. Xiao +2
We report an anomalous matching effect in MoGe thin films containing pairs of circular holes arranged in such a way that four of those pairs meet at each vertex point of a square l…
Enhancing the Critical Current of a Superconducting Film in a Wide Range of Magnetic Fields with a Conformal Array of Nanoscale Holes
Yong-Lei Wang, M. L. Latimer, Zhi-Li Xiao +4
The maximum current (critical current) a type-II superconductor can transmit without energy loss is limited by the motion of the quantized magnetic flux penetrating into a supercon…
Catalyst-Free Growth of Millimeter-Long Topological Insulator Bi2Se3 Nanoribbons and the Observation of pi Berry Phase
L. Fang, Y. Jia, D. J. Miller +5
We report the growth of single-crystalline Bi2Se3 nanoribbons with lengths up to several millimeters via a catalyst-free physical vapor deposition method. Scanning transmission ele…
Large Magnetoresistance Oscillations in Mesoscopic Superconductors Due to Current-Excited Moving Vortices
G. R. Berdiyorov, M. V. Milošević, M. L. Latimer +3
We show in the case of a superconducting Nb ladder that a mesoscopic superconductor typically exhibits magnetoresistance oscillations whose amplitude and temperature dependence are…
