High temperature superconducting (HTS) tapes have crucial applications for generating high magnetic fields with minimal power input. Given a single tape has a limited current-carrying capacity, stacked tapes are common, fabricated through methods like solder soldering or epoxy impregnation requiring heat treatment. In this work, we have investigate...

YBa2Cu3O7 coated conductors are a strategic material for superconducting applications such as high field magnets, fusion, and motors. Grain boundaries reduce the critical current density (Jc) even at a tilt angle as low as 5°, but the successful development of the highly oriented substrates seemed to overcome the weak link problem at grain boundari...

We have investigated the impact of bilayer structures on the critical current density, J c, of YBa2Cu3O6+x (YBCO) coated conductor films, i.e. films grown on buffered metal substrates, under varying temperature and magnetic field conditions. The bilayers consisted of a YBCO layer free of artificial pinning centers and 8 wt% BaZrO3-added (BZO) layer...

V této práci jsme se zaměřili na přípravu a charakterizaci tenkých vrstev vysokoteplotních supravodičů YBCO pomocí metody IJD. V rámci výzkumu jsme připravili celkem 11 vzorků ve dvou sériích, lišících se použitým materiálem substrátu: MgO a SrTiO$_3$. Jednotlivé vzorky v rámci série se lišily teplotou substrátu během depozice. Ta se pohybovala mez...

This contains detailed compositition data from the locations described in the publication. Abstract of related publication: The homogeneity of the microstructure and composition are critical in determining the properties of rare earth-barium-cuprate, single grain bulk superconductors [(RE)BCO]. The magnitude of the trapped magnetic field achieveabl...

High-strength permanent magnets are essential for a wide range of technologies, including levitation devices, motors, generators and magnetic separators. Replacing permanent magnets with single grain, bulk superconductors will enable a step-change in the performance of these technologies by providing an order-of-magnitude increase in magnetic field...

A detailed interpretation of scanning tunneling spectra obtained on unconventional superconductors enables one to gain information on the pairing boson. Decisive for this approach are inelastic tunneling events. Due to the lack of momentum conservation in tunneling from or to the sharp tip, those are enhanced in the geometry of a scanning tunneling...

The emergence of innovative bidimensional materials (2D), coupled with the long-studied High- Tc d-wave superconductors, allows for the development of devices with new functionalities. It however first requires to understand the coupling between these media.This thesis, which encompasses both experiments and their theoretical description, is dedica...

A dataset associated with the listed publication. Trapped field measurements taken as follows: The top and bottom faces of all of the YBCO samples were polished flat and parallel using 180 grit silicon carbide paper. The maximum trapped field at the top and bottom surface was measured initially using a hand-held Hall probe positioned approximately ...
