Magnetic field-tuned magnetic order and metamagnetic criticality in non-stoichiometric CeAuBi
Halyna Hodovanets, Hyunsoo Kim, Tristin Metz +9
We present a detailed study of magnetization, resistivity, heat capacity, and X-ray and neutron powder diffraction measurements performed on single crystals of non-stoichiometric C…
Observation of the superconducting proximity effect in the surface state of SmB6 thin films
Seunghun Lee, Xiaohang Zhang, Yangang Liang +6
The proximity effect at the interface between a topological insulator (TI) and a superconductor is predicted to give rise to chiral topological superconductivity and Majorana fermi…
Ultrafast terahertz spectroscopy study of Kondo insulating thin film SmB: evidence for an emergent surface state
Jingdi Zhang, Jie Yong, Ichiro Takeuchi +2
We utilize terahertz time domain spectroscopy to investigate thin films of the heavy fermion compound SmB6, a prototype Kondo insulator. Temperature dependent terahertz (THz) condu…
Tunable electronic anisotropy in single-crystal A2Cr3As3 (A = K, Rb) quasi-one-dimensional superconductors
X. F. Wang, C. Roncaioli, C. Eckberg +6
Single crystals of A2Cr3As3 (A = K, Rb) were successfully grown using a self-flux method and studied via structural, transport and thermodynamic measurement techniques. The superco…
Robust Surface States indicated by Magnetotransport in SmB6 Thin Films
Jie Yong, Yeping Jiang, Xiaohang Zhang +3
SmB6 has been predicted and verified as a prototype of topological Kondo insulators (TKIs). Here we report longitudinal magnetoresistance and Hall coefficient measurements on co-sp…
Composition-spread Growth and the Robust Topological Surface State of Kondo insulator SmB6 Thin Films
Jie Yong, Yeping Jiang, Demet Usanmaz +7
Topological insulators are a class of materials with insulating bulk but protected conducting surfaces due to the combination of spin-orbit interactions and time-reversal symmetry.…
Anomalously Weak Cooper Pair-breaking by Exchange Energy in Ferromagnet/Superconductor Bilayers
T. R. Lemberger, M. J. Hinton, Jie Yong +3
We report the superconducting transition temperature vs. thickness of Ferromagnet/Superconductor (F/S) bilayers, where F is a strong ferromagnet (Ni, NiFe…
Robustness of the Berezinskii-Kosterlitz-Thouless Transition in Ultrathin NbN Films near the Superconductor-Insulator Transition
Jie Yong, T. Lemberger, L. Benfatto +2
Occurrence of the Berezinskii-Kosterlitz-Thouless (BKT) transition is investigated by superfluid density measurements for two-dimensional (2D) disordered NbN films with disorder le…
Evidence of Two-Dimensional Quantum Critical Behavior in the Superfluid Density of Deeply Underdoped Bi2Sr2CaCu2O8+x
Jie Yong, M. J. Hinton, A. McCray +4
Evidence of two-dimensional (2D) quantum critical fluctuations is observed in the superfluid density ns(T) \propto -2(T) of deeply underdoped Bi2Sr2CaCu2O8+x (Bi-2212) films, i…
Superfluid density in Bi2Sr2CaCu2O8+x from optimal doping to severe underdoping and its implications
Jie Yong, M. Hinton, A. McCray +4
Due to their proximity to an antiferromagnetic phase and to the mysterious pseudogap, underdoped cuprates have attracted great interest in the high Tc community for many years. A c…
Superfluid density measurements of Ba(CoxFe1-x)2As2 films near optimal doping
Jie Yong, S. Lee, J. Jiang +6
We report the first direct measurements of superfluid density, ns(T) \propto λ-2(T), in films of Fe-pnictide superconductors. The magnetic penetration depth, λ(0), in our epitaxial…
