Abstarct: Purpose of this project is growth and magnetic characterization of the Co/Cu/Co nano structure. Among multi-laxyers growth methods, deposition by thermal evaporation method in vacuum is chosen. In order to investigate magnetic and structural properties of three laxyers, laxyers of cobalt and copper with different thicknesses were provided. To study the structure, X-ray diffraction patterns (XRD) was recorded, and morphology of the sample was investigated by field emission scanning electron microscopy (FESEM). Magnetic properties of the samples were measured by vibrating sample magnetometer device (VSM), and magnetoresistance of the samples were measured by van der pauw method. Finally, to evaluate the magnetic anisotropy, near to saturation law was used to fit the magnetic data. X-ray diffraction date showed (111) diffraction peak corresponding to cobalt’s cubic structure (fcc). FESEM images of the samples showed that laxyers with constant, changing the cobalt laxyer thickness don’t affect the morphology of the samples and all samples have uniform surfaces. When the cobalt laxyers thickness was constant, the grain size increases by increasing the copper laxyer thickness and then decreases for thicker samples. The magnetic measurements showed that the easy axis they in he laxyer plane. Also increasing the cobalt’s magnetic laxyer thickness cased increase in saturation magnetization and residual magnetization. The magneto resistance value reduced with increasing the laxyer thickness in both series of the samples. The magnetic anisotropy values obtained from fitting the magnetization data by near to saturation law revealed that the anisotropy increases by increase in cobalt laxyer thickness.
