Abstract:

The present work investigates the texturing and superconducting properties of Sm substituted Bi2Sr2CaCu2O8+δ (Bi-2212) crystals grown by the floating zone technique. The texturing nature of Bi-2212 was quantified by Xray diffraction and by scanning electron microscopic studies. The texturing nature varies with respect to the 'Sm' concentration. Superconductivity studies were carried out by the resistivity technique and the transition temperature increases from 78K to 85K (for x=0.2) and decreases for higher concentration. The c-lattice parameter decreases with Sm substitution. © 2000 Elsevier Science B.V All rights reserved.
