  Electronic phase coherence in normal metals is incredibly sensitive to
magnetic scattering. As a result, the weak localization magnetoresistance and
time-dependent universal conductance fluctuations are powerful probes of
magnetic impurities. We report measurements of these effects in Au and Ag
nanowires with a 1.5 nm thick Ti adhesion layer underneath the deposited metal.
The results indicate an anomalously large magnetic impurity concentration due
to the Ti layer. Results suggest that this magnetic scattering and its
evolution are related to the oxidation state of the Ti.
