TL;DR: In this paper, the surface impedance at 10 GHz was measured systematically in single-crystal (SCL) with carrier concentrations 0.19, from which penetration depth was determined, and the anisotropy and the depencences on x and temperature T were extensively studied for the first time.

TL;DR: In this paper, the crystal structures and superconducting properties of thin films of FeSe$0.5}$Te$ 0.5$ grown on eight different substrates were investigated.

TL;DR: In this paper, the crystal structures and superconducting properties of thin films of FeSe0.5Te 0.5 grown on eight different substrates were investigated, and it was shown that the presence or absence of an amorphous-like layer at the substrate surface plays a key role in determining the structural and superconding properties.

TL;DR: Using Lorentz microscopy to directly image vortices, this work investigates vortex motion control and rectification in a niobium superconductor and creates a tiny vortex "racetrack" to monitor the motion of vortice in a closed circuit channel.

TL;DR: In this article, the in-situ epitaxial growth of FeSe0.5Te 0.5 thin films is demonstrated on a nonoxide substrate CaF2.
