Abstract
We studied the c-axis magnetoresistance (H// ab, J perpendicular to c) of a typical layered perovskite superconducting single crystals Sr2RuO4. It is s hown that the, magnetoresistance is anisotropic and strongly temperature de pendent. When rotating the direction of magnetic field in the ab-plane, the magnetoresistance varies periodically, and the maximum appears as the appl ied ! magnetic field is in the (110) direction. We analyze this transport p roperty with respect to the Fermi surface anisotropy, the quasiparticle sca ttering rate anisotropy and the band dispersion anisotropy, respectively.
