The anisotropic magnetoresistance (MR) of La_(2/3)Ca_(1/3)MnO_3 (LCMO)/YBa_2Cu_4O_8 (YBCO) /LCMO sandwiches on (001) SrTiO_3 were investigated. Single layer LCMO and sandwiches show in-plane anisotropy of MR. MR strongly depends on the magnetic field direction. A nearly sinusoidal dependence on the angle between the applied magnetic field and the film plane or transport current was observed. A positive MR was present with lower fields applied not only out-of-plane but also in-plane.
