Recent advances in rare-earth-free hard-magnetic materials including magnetic bulk, thin
films, nanocomposites and nanostructures are introduced. Since the costs of the rare-earth …

Abstract Calcium phosphate/Cu x Fe 3-x O 4 core-shell nanoceramics have been
synthesized using the organic sol-gel process and calcined at 600 o C. The nanoceramics …

Abstract Undoped, Cu, and Co-doped ZnO nanoparticles were synthesized by a simple co-
precipitation method. We studied the structural, chemical, magnetic, and optical properties of …

This study aims to develop a self-combustion method for use in the preparation of copper
and cobalt ferrites. This development was based on the full use of dry leaves of Corchorus …

Abstract A stable Sr4Fe6O13 was prepared as small crystallites by auto-combustion of a sol-
gel in air followed by annealing the later at pertinent temperatures. A green sample, as …

Abstract Hard Barium ferrite (BaFe 12 O 19) and soft Nickel ferrite (NiFe 2 O 4) nanoparticles
and their nanocomposites with different concentrations, ie (BaFe 12 O 19) 1− x/(NiFe 2 O 4) …

Abstract (MgFe 2 O 4) 100-x/(BaFe 12 O 19) x, soft/hard nanocomposites (NCs) having
different hard ferrite ratio ie x= 0, 25, 50, 75 and 100 have been synthesized via in-situ auto …

Sol-gel auto-combustion synthesis technique was employed to synthesize Cd-Zn ferrite
nanoparticles with composition Zn 1-x Cd x Fe 2 O 4, where 0.0≤ x≤ 1.0. The physical …

In search of efficient ways to produce biodiesel under environmentally friendly conditions,
catalytic reactions have been explored with emphasis on replacing homogeneous by …

Spinel ferrites, especially cobalt ferrite, have the capability of preserving sufficient
magnetization (M s) and coercive field (H c). However, precise nanostructuring is needed to …
