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 . |
