Weak superconducting ceramic link with 90 K in a microwave field
Zavaritskii N. V. , Zavaritskii V. N.
A weak ceramic link with Tc ~ 90 K, which has the characteristics of a single Josephson junction in a 25^4-O-GHz microwave field, has been synthesized. At 77 К the weak link was found to respond to a microwave field up to 3.5 Χ 1012 Hz.
