The Department of Physics at the College of Science – University of Mosul discussed a master’s thesis on Sunday, 15 March 2026, titled: “Preparation of the compound Bi₂₋ₓTeₓBa₂₋ᵧCeᵧCa₂Cu₃O₁₀+δ as a high-temperature superconductor and studying the effect of single and double substitution on its structural, electrical, and dielectric properties.” The thesis was submitted by the student Ibrahim Aziz Ghulam. The study aimed to prepare different samples of the compound Bi₂₋ₓTeₓBa₂₋ᵧCeᵧCa₂Cu₃O₁₀+δ using the solid-state reaction (SSR) technique, with an applied pressure of 7 tons/cm², and employing two thermal treatments—sintering and annealing—in order to investigate the effect of substitution on the structural, electrical, and [Read More]
