Magnetic and Electrical Properties of Nanocrystalline Fe85Si10Ni5/Phenolic Resin Soft Magnetic Composites

In this work, nanocrystalline Fe85Si10Ni5 soft magnetic powders were prepared by mechanical alloying and subsequent annealing to reduce the internal stresses and lattice strains. The powders were mixed with phenolic resin and warm pressed to produce nanostructured soft magnetic composites. The effect of annealing time and temperature on the crystalline structure, microstructure and magnetic pro...

The Electrical Properties of Pure and Doped Nanocrystalline

Nanocrystalline cerium oxide is an attractive material for catalysis of environmentally hazardous gas-phase species such as sulfur dioxide and carbon monoxide. Oxygen vacancies in cerium oxide are believed to coordinate and aid in the transfer of oxygen ions between the reactive species. We have sought to characterize these defects in nanocrystalline cerium oxide as a function of the heat treat...

Effect of Ba Substitution on the Structural and Magnetic Properties of BiFeO3

Bi1−xBaxFeO3 (0 ≤ x ≤ 0.3) nanopowders were synthesized using sol-gel technique. The structural and magnetic properties were investigated using X-ray diffraction, SEM and VSM. As Ba2+ doping concentration was increased, the structure of the samples changed from rhombohedral to tetragonal or monoclinic. The structural change might be an important factor for achieving the ferroelectric properties...
