New Experimental Method for Investigating AC-losses in Concentric HTS Power Cables

, 2015
The optimization of a HTS cable design with respect to AC-losses is of crucial importance for the economic viability of the respective concept. However the experimental determination of AC-losses is not straightforward since for short cable samples the ...

A loss-less superconducting kilo-oersted ac magnetic field system [PDF]

, 1977
A simple superconducting system which allows almost loss-less ac magnetic field to be generated in the kilo-oested region and in the frequency range from dc up to more than 1 kHz is described. The behaviour of commercially available superconducting wires

Lithium Intercalation in the Anisotropic Van Der Waals Semiconductor CrSBr

Advanced Functional Materials, EarlyView.
We report the lithium intercalation in the layered van der Waals crystal CrSBr, revealing strongly anisotropic ion‐migration dynamics. Optical and electrical characterization of exfoliated CrSBr shows lithium diffusion coefficients that differ by more than an order of magnitude along a‐ and b‐directions, consistent with molecular dynamics simulations ...

Transformer Coupling and Its Modelling for the Flux-Ramp Modulation of rf-SQUIDs

Instruments, 2018
Microwave SQUID (Superconducting QUantum Interference Device) multiplexing is a suitable technique for reading a large number of detector channels, using only a few connecting lines. In the HOLMESexperiment, this is based on inductively coupled rf-SQUIDs

Theoretical analysis of drag resistance in amorphous thin films exhibiting superconductor-insulator transitions [PDF]

, 2010
The magnetical field tuned superconductor-insulator transition in amorphous thin films, e.g., Ta and InO, exhibits a range of yet unexplained curious phenomena, such as a putative low-resistance metallic phase intervening the superconducting and the ...

Testing collapse models with levitated nanoparticles: the detection challenge [PDF]

, 2019
We consider a nanoparticle levitated in a Paul trap in ultrahigh cryogenic vacuum, and look for the conditions which allow for a stringent noninterferometric test of spontaneous collapse models.

Role of Liquid Composition in the Transient Liquid Assisted Growth of Superconducting YBa2Cu3O7‐δ Films

Advanced Materials, EarlyView.
The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Fault Current Limitation by 2G HTS Superconducting Transformer - Experimental Investigation

, 2016
Transformers represent one of the oldest and most mature elements in a power transmission and distribution network. The new superconducting transformers are smaller and lighter than conventional ones and they have lower power losses, too.
