Abstract
Proučavamo supravodič-metal prijelaz (SMP) u nanostrukturama od zlata s mrežom tankog filma niobija. Uzorke karakterizira parametar perkolacije p. Mjerenje i analiza provedeni su na šest uzoraka. Za sve uzorke smo izmjerili ovisnost otpora o temperaturi s i bez primjene magnetskog polja kao i njihove IV karakteristike. Analizom R(T) grafova odredili smo vrijednosti otpora u normalnom stanju te temperature supravodljivih prijelaza. Osim toga smo primijetili i zanimljivu anomaliju za koju smo pretpostavili da je potpis proximity efekta. Gornje kritično magnetsko polje dobiveno je ekstrapolacijom WHH i Gorter-Casimir jednadžbi. Provedena je i analiza skaliranja, varijacijom magnetskog polja, iz koje smo dobili vrijednosti produkata kritičnih eksponenata. Na temelju tih vrijednosti odredili smo klase univerzalnosti uzoraka.
Abstract (english)
We study the superconductor-metal transition (SMT) in gold nanostructures with a niobium thin film network. Samples are characterized by the percolation parameter p. The measurement and analysis were carried out on six samples. For all samples, we measured resistance dependence on temperature with and without magnetic field application as well as their I-V characteristics. By analyzing the R(T) graphs, we determined the resistance values in the normal state and the temperature of superconductive transitions. We also noticed an interesting anomaly that we assumed was a proximity effect signature. The upper critical magnetic field was obtained by extrapolation of WHH and Gorter-Casimir equations. A scaling analysis was carried out, by variation of magnetic field, from which we obtained the values of products of critical exponents. Based on these values, we’ve determined the universality classes of the samples.
