Separation of Electron and Hole Dynamics in the Semimetal LaSb
F. Han, J. Xu, A. S. Botana +8
We report investigations on the magnetotransport in LaSb, which exhibits extremely large magnetoresistance (XMR). Foremost, we demonstrate that the resistivity plateau can be expla…
Pinning, Flux Diodes, and Ratchets for Vortices Interacting with Conformal Pinning Arrays
C. J. Olson Reichhardt, Y. L. Wang, Z. L. Xiao +4
A conformal pinning array can be created by conformally transforming a uniform triangular pinning lattice to produces a new structure in which the six-fold ordering of the original…
Enhancing superconducting critical current by randomness
Y. L. Wang, L. R. Thoutam, Z. L. Xiao +6
The key ingredient of high critical currents in a type-II superconductor is defect sites that 'pin' vortices. Contrary to earlier understanding on nano-patterned artificial pinning…
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…
Temperature dependent three-dimensional anisotropy of the magnetoresistance in WTe
L. R. Thoutam, Y. L. Wang, Z. L. Xiao +5
Extremely large magnetoresistance (XMR) was recently discovered in WTe, triggering extensive research on this material regarding the XMR origin. Since WTe is a layered comp…
Stripe Domains and First Order Phase Transition in the Vortex Matter of Anisotropic High-temperature Superconductors
V. K. Vlasko-Vlasov, J. R. Clem, A. E. Koshelev +2
We report the direct imaging of a novel modulated flux striped domain phase in a nearly twin-free YBCO crystal. These domains arise from instabilities in the vortex structure withi…
Doubling the Critical Current Density of High Temperature Superconducting Coated Conductors through Proton Irradiation
Y. Jia, M. LeRoux, D. J. Miller +11
The in-field critical current of commercial YBa2Cu3O7 coated conductors can be substantially enhanced by post-fabrication irradiation with 4 MeV protons. Irradiation to a fluence o…
Direct imaging of hot spots in Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} mesa terahertz sources
T. M. Benseman, A. E. Koshelev, W. -K. Kwok +5
Stacks of intrinsic Josephson junctions (IJJs) made from high-temperature superconductors such as Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} (Bi-2212) are a promising source of coherent continuou…
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…
Tunable terahertz emission from Bi2Sr2CaCu2O8+δ mesa devices
T. M. Benseman, A. E. Koshelev, K. E. Gray +5
We have measured coherent terahertz emission spectra from Bi2Sr2CaCu2O8+δ mesa devices, as a function of temperature and mesa bias voltage. The emission frequency is found to be tu…
Doping and Irradiation Controlled Vortex Pinning Behavior in BaFe2(As1-xPx)2 Single Crystals
L. Fang, Y. Jia, J. A. Schlueter +7
We report on the systematic evolution of vortex pinning behavior in isovalent doped single crystals of BaFe2(As1-xPx)2. Proceeding from optimal doped to ovedoped samples, we find a…
Emission of Terahertz Waves from Stacks of Intrinsic Josephson Junctions
K. E. Gray, L. Ozyuzer, A. E. Koshelev +8
By patterning mesoscopic crystals of Bi2Sr2CaCu2O8 (BSCCO) into electromagnetic resonators the oscillations of a large number of intrinsic Josephson junctions can be synchronized i…
Controlled Dynamics of Interfaces in a Vibrated Granular Layer
I. Aranson, D. Blair, W. Kwok +5
We present experimental study of a topological excitation, {\it interface}, in a vertically vibrated layer of granular material. We show that these interfaces, separating regions o…
Structure of vortex liquid phase in irradiated BSCCO(2212) crystals
N. Morozov, L. N. Bulaevskii, M. P. Maley +4
The c-axis resistivity in irradiated and in pristine BSCCO(2212) crystals is measured as a function of the in-plane magnetic field component at fixed out-of-plane component B_\perp…
