Abstract
We studied phase-coherent phenomena in mesoscopic permalloy (Ni81Fe19) samples by exploring low-temperature transport. Both differential conductance as a function of bias voltage and magnetoconductance of individual wires display conductance fluctuations. Analysis of these fluctuations yields a phase coherence length of ${\approx}$250 nm at 25 mK as well as a 1/sqrt(T) temperature dependence. To ...
