Resumo

This study investigates the effect of various buffer layers on the structure and magnetoresistance of CoFe/Cu superlattices prepared by magnetron sputtering. It has been shown that, in using the (Ni80Fe20)60Cr40 and Ta/(Ni80Fe20)60Cr40 buffer layers, the magnetoresistance at room temperature can exceed 80%. The obtained results have been compared with the data available for superlattices exhibiting the maximum magnetoresistance.
