Two-dimensional magnetic field dependence of zero and finite voltage steps in currentvoltage characteristics of superconducting quantum interference devices
SQUID with two Nb/Al-oxide/Nb junctions fabricated. Josephson current Ic dependence on Hx, Hy external magnetic field was obtained. Finite voltage steps Istep on Hx, Hy external magnetic field was also measured. Resonant electromagnetic field explained the finite voltage steps.
