The depth of this region is known as the London penetration depth.
"The change of the London penetration depth with temperature is directly related to the structure of the so-called superconducting gap, which in turn depends on the microscopic mechanism of how electron pairs are formed," said Prozorov.
"London penetration depth is one of the primary experimentally measurable quantities in superconductor studies," he added.
