Abstract:

An investigation was made of the effect of the weak link current-phase relations on noise in rf biased SQUIDs. Non-sinusoidal current-phase relations have been observed in various weak links and these non-sinusoidal relations have been correlated with significantly increased intrinsic noise in the SQUID ring. The current-phase relation is also found to affect the amplitude of the rf SQUID ring dissipation. The result of a rf SQUID system noise analysis shows that, due to increased intrinsic noise and reduced ring dissipation, the minimum attainable noise for a SQUID ring having a very non-sinusoidal current-phase relation is considably greater than for a ring with a sinusoidal relation.
