The transverse magnetoresistance of single crystals was studied at 1.5K in magnetic fields of up to 60kOe. Open orbits along [110] and [001] were observed for H along Θ=27° (from [001]) in the (1¯10) plane and at most field directions (except near Θ=0°) in the (010) plane, respectively. The [001] direction was a singular field direction. Low frequency oscillations of the order of 104 gauss were superimposed on the monotonie magnetoresistance. The results were consistent with a multiply-connected Fermi surface model that was based upon de Haas-van Alphen experiments.
