Summary

Researchers observed anomalous resonance currents in high-temperature (high- T(c)) direct current (dc) pi superconducting quantum interference devices (SQUIDs). This provides evidence for d-wave symmetry influencing Josephson junction voltage states at high frequencies.

Area of Science:

  • Condensed Matter Physics
  • Superconductivity
  • Quantum Electronics

Background:

  • A direct current pi superconducting quantum interference device (dc pi SQUID) features a superconducting ring with two Josephson junctions.
  • One junction exhibits a pi phase shift due to factors like the d-wave pairing symmetry in high-temperature cuprates.

Purpose of the Study:

  • To investigate the expected anomalous resonance currents in the transport characteristics of dc pi SQUIDs.
  • To provide evidence for the influence of d-wave symmetry on the voltage state of Josephson junctions.

Main Methods:

  • Fabrication and characterization of high-temperature dc pi SQUIDs.
  • Measurement of transport characteristics and identification of resonance currents at GHz frequencies.
