Experimental investigation of resonances in low-Q Josephson interferometer devices
Abstract
Resonance dc structures are experimentally investigated in two-junction interferometers in which the device Q is adjusted to low values with an external resistor connected across the main device inductance. The measurements agree well with the results of a recent analytic theory of interferometer resonances and show that practical interferometer devices with low and adjustable resonance amplitudes can be built.
