Abstract
Structural, magnetic and transport properties of granular CoxCu1-x (x = 0.1 1-0.45) films prepared by e-beam co-evaporation, were studied. Scanning tun neling microscopy showed the surface crystallites having an elongated shape . Magnetization and FMR data indicated a large in-plane uniaxial anisotropy in all the samples. A correlation between the orientation of the surface c rystallites and the anisotropy easy axis has been found. Magnetoresistance in the fields up to 0.5 T is strongly different for transverse and longitud inal geometries. (C) 1999 Elsevier Science B.V. All rights reserved.
