Cryogenic focused-ion-beam microstructuring enabling quantitative -axis transport measurements in TlBaCuO
Ayanesh Maiti, Carsten Putzke, Linus Holeschovsky +10
Absolute transport measurements in correlated quantum materials are often limited by disorder, inhomogeneity, geometric uncertainty, and small crystal size. Focused ion beam (FIB)…
Emergence of superconductivity in single-crystalline LaFeAsO under simultaneous Sm and P substitution
Nikolai D. Zhigadlo, Roman Puzniak, Philip J. W. Moll +2
We report on the high-pressure growth, structural characterization, and investigation of the electronic properties of single-crystalline LaFeAsO co-substituted by Sm and P, in both…
Controlling superconductivity of CeIrIn microstructures by substrate selection
Maarten R. van Delft, Maja D. Bachmann, Carsten Putzke +5
Superconductor/metal interfaces are usually fabricated in heterostructures that join these dissimilar materials. A conceptually different approach has recently exploited the strain…
Spatially modulated heavy-fermion superconductivity in CeIrIn5
Maja D. Bachmann, G. M. Ferguson, Florian Theuss +20
The ability to spatially modulate the electronic properties of solids has led to landmark discoveries in condensed matter physics as well as new electronic applications. Although c…
Critical fields and fluctuations determined from specific heat and magnetoresistance in the same nanogram SmFeAs(O,F) single crystal
Stanislaw Galeski, Philip W. J. Moll, N. D. Zhigadlo +2
Through a direct comparison of specific heat and magneto-resistance we critically asses the nature of superconducting fluctuations in the same nano-gram crystal of SmFeAs(O, F). We…
