The flux noise power spectra of SQUIDs go as $1/f^\\alpha$, where $\\alpha$ is the temperature-dependent noise exponent. Experiments find $0.5 \\lesssim \\alpha \\lesssim 1$. Furthermore, experiments find that the noise power spectra versus frequency at different temperatures pivot about or cross at a common point for each SQUID.
