Abstract A number of structural analysis methods were employed to investigate the microstructures of ion-beam co-sputtering of Co x Ag1−x (0⩽x⩽100 at%) granular films. Forx=22 at%, the sample which has the optimal giant magnetoresistance at room temperature, there exists either crystallized or highly disordered regions shown by high-resolution electron microscopy. At the boundary between cobalt granules and the silver matrix, lattice mismatch was formed, leading to roughness of the interfaces. X-ray diffraction and transmission electron microscopy revealed that the samples had f c c structure at lowx, with (111) texture, and the h c p structure gradually appeared as x〉75 at %. Relative lattice expansion was observed asx increased.
