Unusual persistence of superconductivity against high magnetic fields in the strongly-correlated iron-chalcogenide film FeTe:O
I. K. Dimitrov, W. D. Si, W. Ku +2
We report an unusual persistence of superconductivity against high magnetic fields in the iron chalcogenide film FeTe:O below ~ 2.5 K. Instead of saturating like a mean-field…
Transport Properties of Stripe-Ordered High Tc Cuprates
Qing Jie, Su Jung Han, Ivo Dimitrov +2
Transport measurements provide important characterizations of the nature of stripe order in the cuprates. Initial studies of systems such as La(1.6-x)Nd(0.4)Sr(x)CuO(4) demonstrate…
Local Structure of the Superconductor K0.8Fe1.6+xSe2: Evidence of Large Structural Disorder
T. A. Tyson, T. Yu, S. J. Han +4
The local structure of superconducting single crystals of K0.8Fe1.6+xSe2 with Tc = 32.6 K was studied by x-ray absorption spectroscopy. Near-edge spectra reveal that the average va…
Iron-chalcogenide FeSeTe coated superconducting tapes for high field applications
Weidong Si, Juan Zhou, Qing Jie +7
The high upper critical field characteristic of the recently discovered iron-based superconducting chalcogenides opens the possibility of developing a new type of non-oxide high-fi…
Direct Evidence for Edge-Contaminated Vortex Phase in a Nb Single Crystal using Neutron Diffraction
Helen A. Hanson, Xi Wang, Ivo K. Dimitrov +7
We report the first direct observation of a disordered vortex matter phase existing near the edge of a bulk type-II superconductor Nb using a novel position-sensitive neutron diffr…
Magnetocaloric Studies of the Peak Effect in Nb
N. D. Daniilidis, I. K. Dimitrov, V. F. Mitrovic +2
We report a magnetocaloric study of the peak effect and Bragg glass transition in a Nb single crystal. The thermomagnetic effects due to vortex flow into and out of the sample are…
