✦ Synopsis

It has been found that superconducting thin films in the resistive current state can initiate, in addition to Josephson oscillations, non-Josephson oscillation (NJ01 of much lower frequencies (106-lo8 Hz). Characteristically, the NJ0 frequency f. is extremely sensitive to external parameters such as d.c. current, temperature and infrared (IR) irradiation. This high sensitivity of the oscillation frequency to external influences holds much promise for the development of a new class of detectors. The present work was performed using the temperature sensitivity of the effect, which may be as high as IO" Hz K-l, and then considering the possibility of developing an IR bolometer.

In this work we show that with strong hydrogen bonds, including a 'very strong' hydrogen bond and/or strong hydrogen-bonding networks, highly non-linear optically active chromophores, merocyanine dyes and phenol derivatives, are assembled as salt or semi-salt crystals, leading to improvement in crys
