1. Unconventional Properties of YBCO Thin Films and GB Josephson Devices for Novel Applications
Sammanfattning : .... LÄS MER
2. Noise and electrical properties of YBCO nanostructures
Sammanfattning : This thesis work deals with the investigation of noise properties in cuprate High critical Temperature Superconductor (HTS) YBCO nanoscale devices. Here the aim is to get a better understanding of nanoscale fluctuations in the normal state of HTS from which superconductivity evolves. LÄS MER
3. Resistivity and the solid-to-liquid transition in high-temperature superconductors
Sammanfattning : In high-temperature superconductors a large region of the magnetic phase diagram is occupied by a vortex phase that displays a number of exciting phenomena. At low temperatures, vortices form a truly superconducting solid phase which at high temperatures turns into a dissipative vortex liquid. LÄS MER
4. On the Zero and Low Field Vortex Dynamics : An Experimental Study of Type-II Superconductors
Sammanfattning : Dynamic properties of type-II superconductors have been experimentally studied in zero and low magnetic fields using SQUID magnetometry and I–V measurements.In zero magnetic field close to the critical temperature, the physical properties of type-II superconductors are dominated by spontaneously created vortices.

5. Approaching the depairing critical current in superconducting YBa2Cu3O7−x nanowires
Sammanfattning : The microscopic origin of High critical Temperature Superconductivity isstill an open issue in condensed matter physics. In these complex oxideselectrons self-organize in ways qualitatively different from those of conventionalmetals and insulators. LÄS MER
