Abstract

The samples of Eu2-xCexCuO4 (ECCO) with x = 0.09 (Eu1.91Ce0.09CuO4) and x = 0.16 (Eu1.84Ce0.16CuO4) have been synthesized by the solid reaction method without annealing. Each sample is covered with CuO to prevent excess oxygen entering the sample. The purity and electrical resistivity were investigated by x-ray Diffraction (XRD) and resistivity measurements. From the XRD analysis, it was found that the purity of ECCO phase was 93.5% with tetragonal structure of T’ for x = 0.09 while 96.1% for x = 0.16. These results show that the synthesis method with CuO covering has succeeded in synthesizing materials with high purity. From the electrical measurements, the trace of superconductors was not observed in all samples. It is probably the existence of excess oxygen, which was not fully absorbed by CuO Covering.
