Briefings

Adelaide University researchers developed a superconducting sensor design that identifies zero magnetic fields while maintaining maximum sensitivity. The breakthrough replaces complex multi-loop arrays with a simpler structure using bare superconducting loops, which function as an array of different loop sizes. This approach was experimentally confirmed at very low temperatures and is published in Physical Review Applied. The discovery addresses a long-standing limitation where traditional SQUIDs struggle to detect exact zero magnetic fields, which is critical for applications in brain imaging, communications, and electromagnetic sensing.

Key points

• Researchers replaced complex multi-loop arrays with a simpler design using bare superconducting loops to identify zero magnetic fields.
• The new design was experimentally confirmed at very low temperatures and is published in Physical Review Applied.
