Close to a zero-temperature transition between ordered and disordered electronic phases, quantum fluctuations can lead to a strong enhancement of electron mass and to the emergence of competing phases such as superconductivity. A correlation between the existence of such a quantum phase transition and superconductivity is quite well established in some heavy fermion and iron-based superconducto...
Direct electron-beam irradiation of high-Tc thin films has been used to create closely spaced Josephson junctions which operate at temperatures of 60-80 K. The electrodynamics of two junctions have been investigated by studying the dependence of the critical current on an applied magnetic field. The junctions spaced between 50 and 150 nm could be measured independently by using a narrow third e...
High-resolution focused ion beam lithography has been used to fabricate YBa₂Cu₃O7-x (YBCO) wires with nanometric lateral dimensions. In the present work, we investigate Flux-flow instabilities in nanowires of different widths, showing sudden voltage switching jumps from the superconducting to the normal state. We present an extensive study on the temperature and field dependence of the switchin...
This work discusses the development of an analysis routine for evaluating nanoparticle distribution in nanocomposite thin films. YBa2Cu3O7−δ (YBCO) films were synthesized via a chemical solution deposition approach starting from colloidal YBCO solutions with preformed nanoparticles. The nanoparticles and interlayer diffusion are evaluated X-ray photoelectron spectroscopy (XPS) depth profiling c...
