The present paper reports results on the Gd-doped Co–Cu granular alloys and metallic glasses prepared by different processing methods. The main aim of this research was to produce a ternary alloy which radically changes its magnetoresistance (MR) properties below critical temperature. A detailed study on the evolution of the structure and phase separation is presented basing on X-ray diffractometry (XRD) analysis and scanning electron microscopy (SEM) observation. MR was measured by means of a two point probe method in magnetic field using a new experimental device which was patented thereafter.
