Abstract

The effects of Cr in ErBa2(Cu1-xCrx)O7-δ (x=0-0.1) superconductor have been investigated. The critical temperature, which was determined by DC electrical resistance measurements, showed no suppression of the onset temperature (Tc onset) within the substitution range. The transition width (ΔTc) broadened as the Cr content is increased. The normal state changes from the metal-like to semimetal/semiconductor-like for x≥0.03. Micrographs from the scanning electron microscope, X-ray diffraction pattern, and energy dispersive X-ray analysis results are used to describe the superconducting properties of these materials. The orthorhombic structure was preserved throughout the substitution range. Some possible roles of Cr in the system are discussed.
