Effect of Eu doping on structural and magneto-electrical properties of La0.7Ca0.3MnO3 manganites

Altıntaş, Sevgi Polat; Amira, A.; Mahamdioua, N.; Varilci, Ahmet; Terzioğlu, Cabir (Elsevier Science Sa, 2011)

We have investigated the influence of europium (Eu) doping on structural and magneto-electrical properties of La0.7Ca0.3MnO3 compounds. In order to analyze the physical mechanism of a spin disorder system and study their ...
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 ...
Substitution effect of Sr2+ by Ca2+ on structure and superconducting properties of Bi2Sr1.6La0.4CuO6+? (Bi-2201) ceramics

S., Boudjaoui; Amira, A.; Mahamdioua, N.; Altıntaş, Sevgi; Varilci, Ahmet; Terzioğlu, Cabir (Elsevier B.V., 2018)

In this work, the effect of Ca2+ iso-valence substitution for Sr2+ on properties of Bi2Sr1.6La0.4CuO6+? superconductors is presented. Samples series with nominal composition of Bi2Sr1.6-xCaxLa0.4CuO6+? (x= 0, 0.2, 0.4, 0.6 ...
