Abstract

A series of e-beam evaporated [Co10 angstrom/Aut angstrom](20) multilayers has been deposited on 1.69 mm(2) glass substrates. The samples were examined with vibrating sample magnetometer, low angle X-ray diffraction, and magnetoresistance (MR) measurements. The effects of oblique incidence evaporation and magnetic annealing on the anisotropy, microstructure, and different components of MR are examined. After magnetic annealing, the multilayer [Co10 angstrom/Au20 angstrom](20) produced at the incidence angle of 45 degrees showed a strong anisotropy and the easy axis of the anisotropy is along the perpendicular (x-axis; along the film plane) to the incidence of evaporation. MR at room temperature has two components: isotropic and anisotropic. The magnetoresistance effects are found to be larger in the uniaxial films, with both anisotropic and giant magnetoresistance peaking at around 20 angstrom Au layer thickness. (C) 2006 Elsevier B.V.
