The in-plane and out-of-plane magnetoresistances of moderately overdoped Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8+x/ single crystals have been studied from T/sub c/+5 K to T/sub c/+100 K with the magnetic field oriented perpendicular and parallel to the current, respectively. The in-plane magnetoresistance is positive, the out-of-plane magnetoresistance negative, and their temperature variations depend on the orientation of the magnetic field. A recent theory for superconducting order parameter fluctuations is extended for the interaction of carrier spins with the magnetic field. The anomalous, anisotropic magnetoresistance can be described well by a unique set of physical parameters, which were found to correspond to estimates from the normal-state transport properties.
