摘要: We present a comparative study of existing low‐frequency noise reduction techniques for dc superconducting quantum interference devices (SQUIDS). These methods are essential to applications involving high‐Tc SQUIDS because they dramatically reduce the 1/f useful levels. propose formal presentation problem and explain mathematically working principles these reductions methods, particularly fluctuations arising from critical current junctions. An increase in white level is generally observed when sinusoidal lock‐in detection used we give here mathematical explanation this peculiar effect. Finally, measurements made on grain boundary presented; experimental results close agreement with theory.
