One of the major drawbacks for applications of high-temperature superconducting films is that magnetic flux is not completely expelled but penetrates the film in the form of flux vortices. Any motion of these vortices is accompanied by magnetic noise

We report on the influence of YBa2Cu3O7−δ (YBCO) thin films on the self-organized formation of gold nanoparticles. A thickness variation of the YBCO film allows one to actively control the size of the particles and their density distribution. In t

We present a possible fabrication scheme of anisotropic nanoparticles grown in a crystal high-index material (SrTiO3). Different ellipsoidal Au nano-antennas were formed by changing the Au seed layer thickness and subsequent embedding in SrTiO3, prep

Crystalline Au nanoparticles embedded in epitaxially grown SrTiO3 layers were prepared by an annealing and coating procedure of Au seed layers on SrTiO3 (STO) substrates. X-ray diffraction and transmission electron microscopy measurements were perfor

Although several instruments to assess cyberbullying have been developed, there is nevertheless a lack of knowledge about their psychometric properties. The aim of the present systematic review is to provide a representative overview of the current i

Adding Au nanoparticles to YBa${}_{2}$Cu${}_{3}$O${}_{7\ensuremath{-}\ensuremath{\delta}}$ thin films leads to an increase of the superconducting transition temperature ${T}_{\mathrm{c}}$ and the critical current density ${j}_{\mathrm{c}}$. While the
