Dielectric properties and nonlinear electrical characteristics of (Mg2+, Ta5+) co-doped Bi2/3Cu3Ti4O12 ceramics

Investigating the impact of Sm3+/Ni2+ co-doping on the dielectric behaviour of CaCu3Ti4O12 ceramics for microelectronic applications

Dielectric properties and nonlinear electrical behavior of CaCu3Ti4−x(Sb1/2Ta1/2)xO12 ceramics

CaCu3Ti4O12 (CCTO) ceramics exhibit giant permittivity; however, achieving low dielectric loss (tan δ) together with balanced electrical performance remains challenging for practical applications. In this work, Sb3+ and Ta5+ were co-doped at the Ti-site of CaCu3Ti4−x(Sb1/2Ta1/2)xO12 (x = 0–0.2) to tailor the defect che...

Bi doping enhances the thermoelectric properties of tetragonal tungsten bronze Sr0.7Ba0.3Nb2O6 ceramics

Effects of Ni2+ and Cr3+ Substitution at Mn-Site on Structural and Electrical Resistivity of Charge Ordered Divalent-Doped Sm0.5Ca0.5MnO3 Manganite

Perovskite manganites (R1-xAxMnO3) are widely studied for their unique magneto-transport properties, especially the metal-insulator transitions. Sm0.5Ca0.5MnO3 is a prototypical half-doped manganite known for its strong charge-ordering (CO) behaviour and high CO temperature (TCO ≈ 270 K), which limits its practical app...

Effect of La Doping on Structural and Superconducting Properties of (Bi, Pb)-2223 Ceramics

Superconducting ceramics with nominal composition Bi1.6Pb0.4Sr2Ca2-yLayCu3O10+d (0 ≤ y ≤ 0.04); were prepared in pellet form by conventional solid-state reaction method. The samples were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), temperature-dependent resistivity measurements,...
