Theeffect ofTa205additiveon the electric and magnetic properties of MnZn ferrites with fine grain size was studied Aadding small amounts ofTa205 to the MnZn ferriteincreased electric resistivity, while an excessive addition of Ta205causeddecreasein resistivity without significant grain growth. In asmall amount ofTa205 the change in the electric resistivity can be explained by ~ a ' ' substituti...
متن کاملSynthesis and structural properties of Mn-doped ZnO/Graphene nanocomposite
Zinc oxide (ZnO) is a promising metal oxide semiconductor with various applications, especially in the photocatalytic destruction of environmental pollutants. However, this nanoparticle has some limitations, such as poor dispersion, aggregation, and a wide energy gap. As such, the doping of metal oxide semiconductor has been strongly recommended. Addition of manganese (Mn) has proven effective ...

متن کاملEnhanced Photovoltage Response of Hematite-X-Ferrite Interfaces (X = Cr, Mn, Co, or Ni)
High-fluorescent p-X-ferrites (XFe2O4; XFO; X = Fe, Cr, Mn, Co, or Ni) embedded in n-hematite (Fe2O3) surfaces were successfully fabricated via a facile bio-approach using Shewanella oneidensis MR-1. The results revealed that the X ions with high/low work functions modify the unpaired spin Fe2+-O2- orbitals in the XFe2O4 lattices to become localized paired spin orbitals at the bottom of conduct...
