Structural and Magnetic Properties of Pb-substituted CuFe2O4 Nanoparticles

Lead-substituted copper ferrites (Cu1-xPbxFe2O4, x = 0.0–0.30) were synthesized via a sol–gel auto-combustion route to explore the structural and magnetic effects of Pb²⁺ incorporation. X-ray diffraction confirmed a tetragonal spinel phase (I41/amd) for low Pb content, which grad...

Hierarchical graphene oxide/Co-metal-organic framework/Fe₃O₄ structures for high-performance applications

Metal–organic frameworks (MOFs) and ferrites face drawbacks such as poor conductivity and self-aggregation. Optimized synthesis methods partially alleviate these issues, while a complementary strategy is to design nanocomposites that integrate both materials. We engineer three-di...
