We find that the AMR changes sign from negative ($\\rho_{||}<\\rho_{\\perp}$) at high temperatures to positive ($\\rho_{||}>\\rho_{\\perp}$) at low temperatures. The temperature, T$_s$, at which this sign change occurs, decreases with increasing film thickness $t$ and T$_s$ vanishes for $t$ $>$ 30 nm. We interpret our results in the framework of a competition between two components: a negative bulk contribution and a positive surface AMR.","authors_text":"A. Kohn, G. Levi, M.
