Penetration of a magnetic field into a regular 3D array of superconductor nanoparticles
Romanov S. G.
An oscillatory component of the critical current and the resistance as a function of the magnetic field has been detected in a regular 3D array of close-packed, weakly linked superconductor nanoparticles. The observed oscillation spectrum is interpreted as being related to a quantization of magnetic flux in a system of loops which can be distinguished in such a lattice.
