  • Abstract
    MgB2/Al/AlN/MgB2 Josephson junctions were fabricated on c-plane sapphire substrates. The current-voltage characteristics of the junctions were over-damped characteristics without any excess current. The critical current was ideally modulated by applying an external magnetic field. By the evaluation of the junction uniformity of 11- and 101-arrayed junctions, 1sigma values of 7.9% and 10.2% were obtained. For parallel junctions, clear current modulations were observed on applying a magnetic field.
