Electronic interactions between gold films and mn12-acetate
Abstract
Interactions between Mn12–acetate molecular magnets and thin gold films have been explored
in light of the theory of weak localization. Low-temperature measurements of the
magnetoresistance of gold films of varying thicknesses, with and without the presence of a
surface layer of Mn12–acetate, have been performed using a dilution refrigerator. Quantitative
fits to the data using the predictions of weak localization theory were performed using
a least-squares fit method in order to determine characteristic times for elastic, inelastic,
spin-orbit and spin scattering events within the gold. These data indicate that the presence
of Mn12–acetate on the surface of the gold film leads to a significant enhancement of the
spin scattering within the gold films.
