Effect of doping by low content of yttrium at Ca and Sr sites of Bi(Pb)-2212 superconducting ceramics
Amira, Abderrezak; Boudjadja, Y.; Saoudel, A.; Varilci, Ahmet; Akdoğan, Mustafa; Terzioğlu, Cabir (Elsevier, 2011)In this work, a comparative study of the effect of doping bylaw content of Y3+ between (Ca site) and out of (Sr site) the CuO2 planes of Bi(Pb)-2212 phase is presented. Ceramics of Bi1.6Pb0.4Sr2Ca1-xYxCu2O8+d (called CY ... -
Effect of fluorine doping on phase formation and properties of Bi(Pb)-2223 ceramics
Amira, A.; Saoudel, A.; Boudjadja, Y.; Amirouche, L.; Mahamdioua, N.; Varilci, Ahmet; Akdoğan, Mustafa; Terzioğlu, Cabir (Elsevier Science Bv, 2011)Superconducting ceramics of Bi1.6Pb0.4Sr2Ca2Cu3OyFx (x = 0-0.6) are prepared in air by conventional solid state reaction and characterized. The study shows that the melting point of the samples decreases as fluorine content ... -
Effects of thallium fluoride and yttrium on structure, electrical properties and ac losses susceptibility of (Bi,Pb)-2234 superconductors
Saoudel, A.; Saoudel, Assia; Boudjadja, Y.; Bouchekhou, H.; Allag, H.; Altıntaş, Sevgi Polat (Elseiver Science Ltd, 2021)We have studied the effects of thallium fluoride TlF3 and yttrium Y3+ on phase formation and superconducting transport properties of Bi1.8_xTlxPb0.35Sr2Ca3_ zYzCu4O12+delta F3x superconductors. The samples are characterized ... -
Microstructural and magneto-transport properties of Bi1.6Pb0.4Sr2Ca1-xGdxCu2O8+delta superconducting ceramics
Boudjadja, Yazid; Amira, Abderrezak; Mahamdioua, Nabil; Saoudel, A.; Menassel, S.; Varilci, Ahmet; Terzioglu, Cabir; Altıntaş, Sevgi Polat (Elsevier, 2017)This study aims to investigate the effect of Gd doping on the phase formation, microstructure, transport and magnetic properties of the Bi(Pb)-2212 system. A series of superconducting bulks with a nominal composition of ... -
Structural and magneto-transport properties of copper doped double layered manganites La1.4Ca1.6Mn2O7
Mahamdioua, Nabil; Amira, Abderrezak; Altıntaş, Serpil Polat; Saoudel, A.; Boudjadja, Yazid; Varilci, Ahmet; Terzioğlu, Cabir (Springer, 2013)Samples of La1.4Ca1.6Mn2-xCuxO7 with 0 <= x <= 0.075 were prepared by a solid state reaction and characterized. The cell parameters and volume increase with increasing doped content in all the samples. The metal-insulator ...
