抄録

Effects of correlation of the spin scattering between different measurements in the presence of the spin glass ordering have been investigated for mesoscopic fluctuations of Josephson currents in SNS junctions and those of persistent currents in isolated Aharonov-Bohm (AB) rings. It is found that, because of the absence of the time reversal symmetry, fluctuations of Josephson currents do not vanish even if the phase difference of two superconductors is zero and those of persistent currents in the absence of AB flux is also not zero. Moreover the characteristic length of exponential decay of the fluctuation of Josephson currents can be much longer than that of the average.
