ABSTRACT
The angular dependence of the magnetoresistance of polycrystalline Y3/4Lu1/4Ba2Cu3O7-CuO composites has been studied. These composites represent a system of Josephson junctions and exhibit a large magnetoresistance at 77 K. In addition to the isotropic component, there is the angle-dependent component proportional to sin2Ï‘, where Ï‘ is the angle between the directions of current and magnetic field. This behavior is unambiguous evidence for the process of flux flow in the Josephson medium realized in the composites.
