Ion-beam Assisted Sputtering of Titanium Nitride Thin Films
Timothy Draher, Tomas Polakovic, Juliang Li +10
Titanium nitride is a material of interest for many superconducting devices such as nanowire microwave resonators and photon detectors. Thus, controlling the growth of TiN thin fil…
Tunable magnetically induced transparency spectra in magnon-magnon coupled Y3Fe5O12/permalloy bilayers
Yuzan Xiong, Jerad Inman, Zhengyi Li +13
Hybrid magnonic systems host a variety of characteristic quantum phenomena such as the magnetically-induced transparency (MIT) and Purcell effect, which are considered useful for f…
Strong magnon-photon coupling in ferromagnet-superconducting resonator thin-film devices
Yi Li, Tomas Polakovic, Yong-Lei Wang +13
We demonstrate strong magnon-photon coupling of a thin-film permalloy device fabricated on a coplanar superconducting resonator. A coupling strength of 0.152 GHz and a cooperativit…
Glassy Dynamics in a heavy ion irradiated NbSe2 crystal
Serena Eley, Karen Khilstrom, Roxana Fotovat +7
Fascination with glassy states has persisted since Fisher introduced the vortex-glass as a new thermodynamic phase that is a true superconductor that lacks conventional long-range…
Effect of hexagonal patterned arrays and defect geometry on the critical current of superconducting films
I. A. Sadovskyy, Y. L. Wang, Z. -L. Xiao +2
Understanding the effect of pinning on the vortex dynamics in superconductors is a key factor towards controlling critical current values. Large-scale simulations of vortex dynamic…
Origin of the turn-on temperature behavior in WTe
Y. L. Wang, L. R. Thoutam, Z. L. Xiao +8
A hallmark of materials with extremely large magnetoresistance (XMR) is the transformative 'turn-on' temperature behavior: when the applied magnetic field is above certain valu…
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…
Evaluating free flux flow in low-pinning molybdenum-germanium superconducting films
Manlai Liang, Milind N. Kunchur, Jiong Hua +1
Vortex dynamics in molybdenum-germanium superconducting films were found to well approximate the unpinned free limit even at low driving forces. This provided an opportunity to emp…
Nickel Antidot Arrays on Anodic Alumina Substrates
Z. L. Xiao, Catherine Y. Han, U. Welp +8
Large area nickel antidot arrays with density up to 10^10 /cm^2 have been fabricated by depositing nickel onto anodic aluminum oxide membranes that contain lattices of nanopores. E…
Superconducting Transition and Vortex Pinning in Nb Films Patterned with Nano-scale Hole-arrays
U. Welp, Z. L. Xiao, J. S. Jiang +6
Nb films containing extended arrays of holes with 45-nm diameter and 100-nm spacing have been fabricated using anodized aluminum oxide (AAO) as substrate. Pronounced matching effec…
Edge and Bulk Transport in the Mixed State of a Type-II Superconductor
Z. L. Xiao, E. Y. Andrei, Y. Paltiel +3
By comparing the voltage-current (V-I) curves obtained before and after cutting a sample of 2H-NbSe2, we separate the bulk and edge contributions to the transport current at variou…
Instabilities and disorder-driven first-order transition of the vortex lattice
Y. Paltiel, E. Zeldov, Y. Myasoedov +8
Transport studies in a Corbino disk geometry suggest that the Bragg glass phase undergoes a first-order transition into a disordered solid. This transition shows a sharp reentrant…
Equilibration and Dynamic Phase Transitions of a Driven Vortex Lattice
Z. L. Xiao, E. Y. Andrei, P. Shuk +1
We report on the observation of two types of current driven transitions in metastable vortex lattices. The metastable states, which are missed in usual slow transport measurements,…
Flow Induced Organization and Memory of a Vortex Lattice
Z. L. Xiao, E. Y. Andrei, M. J. Higgins
We report on experiments probing the evolution of a vortex state in response to a driving current in 2H-NbSe crystals. By following the vortex motion with fast transport measur…
