Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions

Advanced Materials, EarlyView.
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.

Electromagnetic Characterization and Parameter Calculation of the Superconducting Ultra-high Voltage Synchronous Condenser

Journal of Harbin University of Science and Technology
The superconducting ultra-high voltage synchronous condenser adopts high-voltage cable winding as stator winding, which can be directly connected to the power grid without a step-up transformer, and the special structure of its stator with non-magnetic ...

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

Superconducting traction transformer: traction - the HTS transformer killer application? [PDF]

, 2021
An ongoing project to develop HTS traction transformers for the Chinese Fuxing high-speed train is demonstrating that the high power density accessible using high temperature superconductors (HTS) can produce spectacular results: the existing 6.5 MVA traction transformers can be replaced with drop-in superconducting transformers which can achieve ...

Activating a Metallization Switch for Record Hydrogen Evolution in Single‐Atom Modified Polar MOF Piezocatalysts

Advanced Materials, EarlyView.
ABSTRACT Piezocatalytic hydrogen evolution enables the conversion of mechanical energy into chemical fuels, but its efficiency is constrained by a trade‐off between piezoelectric polarization and electronic conductivity. Strong piezoelectric polarization is essential for sufficient driving force, yet highly polar materials typically suffer from poor ...

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...
