High-field magnetoresistance and Shubinikob-de Haas (SdH) effects were studied in the A15 compound Nb/sub 3/Sb in fields up to 215 kG. A change in the field dependence of the magnetoresistance for certain field directions above about 150 kG appears to signal the onset of magnetic breakdown. Five sets of SdH frequencies were observed, four of them closely corresponding to de Haas-van Alphen (dHvA) frequencies observed by Arko et al. The fifth frequency has an extremely large amplitude, about 20% of the background magnetoresistance, and it is suggested that this also is due to magnetic breakdown. The results are compared with the ab initio band calculations of van Kellel et al., which can explain many of the observed features of the dHvA and SdH frequencies.
