Abstract
We report anomalies in the weak localisation (wl) effect and strong deviati ons from the Kohler rule (DKR) in the classical magnetoresistance of antimo ny wires of cross-sections down to 30 x 100 nm(2) in the fields up to 5 T i n the temperature interval of 0.27-10 K. A strong anisotropy of the Fermi s urface generic to semi-metals and reflections at grain boundaries are sugge sted to account for DKR. There is probably a link between the DKR and the w l anomalies.
