The flow of current between the superconductors in the absence of an applied voltage is called a Josephson current and the movement of electrons across the barrier is known as Josephson tunneling [2, 3].
My first objective is to study the competition/cooperation between the magnetic and the superconducting correlations induced in the electrons of the nanoscopic metallic island by measuring the amplitude and phase of the superconducting Josephson current. Secondly, I will investigate the effect of the magnetic impurities on the quasi-electrons density of states in such junction.
At each of the peak voltages, the frequency of the AC Josephson current resonates with the vibrational frequency of the nanstructure in the junction.
