THE BOLOMETRIC RESPONSE OF SUPERCONDUCTIN G FILM TO EXTERNAL IR RADIATION IN THE NON-JOSEPHSON OSCILLATION REGIME

It is found that superconducting thin films in the resistive current s tate can initiate, in addition to the Josephson oscillations, those of much lower frequencies (10(6)-10(8) Hz) the non-Josephson oscillation s (NJO). Typically, the NJO frequency f(g) is extremely sensitive to e xternal parameters - dc current, temperature and electromagnetic irrad iation. The high sensitivity of the oscillation frequency to external influence holds much promise for development of a new class of detecto rs. The response of the superconducting film to external IR radiation in the non-Josephson oscillation regime has been investigated and the bolometric characteristics of such film have been estimated.
