Problems of anysotropy in MgB2 superconductor

2003
Mjerili smo mikrovalnu vodljivost tankog filma MgB2 u ovisnosti o temperaturi i primijenjenome vanjskome magnetskom polju. Dobivene rezultate analizirali smo s pomoću modela efektivne vodljivosti[1]. Odredili smo duljinu koherencije i frekvenciju zapinjanja za svaku vrijednost kompleksne efektivne vodljivosti izmjerenu pri određenoj temperaturi i ...

Spin injection at MgB2-superconductor/ferromagnet interface

Applied Physics Letters
There is a growing interest in mixing spintronics and superconductivity to develop original energy-efficient nonvolatile memory and logic devices. Research works conducted so far have mostly focused on superconductor with critical temperature Tc lower than 10 K.

Coherence lengths and anisotropy in MgB2 superconductor

Physical review. B, Condensed matter and materials physics, 2003
Field and temperature microwave measurements have been carried out on MgB2 thin film grown on Al2O3 substrate. The analysis reveals the mean field coherence length in the mixed state and a temperature independent anisotropy ratio 2. At the superconducting transition, the scaling of the fluctuation conductivity yields the Ginzburg-Landau coherence ...
