Monotonic decrease of Tcs with thinning of the superconducting MgB2 layer in MgB2/Ni and MgB2/B alternately-layered thin films
We prepared MgB2/Ni and MgB2/B alternately-layered films using electron beam evaporation and coaxial vacuum arc evaporation techniques without any post-annealing. The thickness of each MgB2 layer was designed to be 42, 24 or 15 nm for both MgB2/Ni and MgB2/B alternately-layered films. We confirmed t...
