nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing energy and stopping its loss is one of enthusiastic projects in new science. thus; alloys produced by electrochemical and pure methods have been discussed in this thesis. in this research, the prepared samples was studied using x-ray diffraction (xrd) and scanning electron microscopy (sem) and following them the vibrating sample magnetometer (vsm) analysis was used to describe the magnetic properties of samples at room temperature. the results indicate that our samples are free of energy loss. the grain size of produced alloys by electrochemical method are in around of nano scale which is in the limit of soft ferromagnetic materials which they research for saturation in low magnetization. however the samples prepared from pure powder of ni and cu shows supperparamagnetic behaviors.
