The anisotropic magnetoresistances (AMRs) in single crystalline Co(6 nm)/SrTiO3(001) heterostructures from 5 K to 300 K with the current direction setting along either Co[100]or Co[110]are investigated in this work.The anomalous(normal) AMR is observed below (above) 100 K.With the current along Co[100]direction,the AMR shows negative longitudinal and positive transverse magnetoresistances at T < 100 K,while the AMR is inverse with the current along Co[110].Meanwhile,the amplitude ratio between Co[110]and Co[100]is observed to be as large as 29 at 100 K.A crystal symmetry-adapted model of AMR demonstrates that interplay between the non-crystalline component and crossed AMR component results in the anomalous AMR.Our results may reveal more intriguing magneto-transport behaviors of film on SrTiO3 or other perovskite oxides.
