- W2990757941 abstract "We report on tunable band engineering of $alpha-mathrm{Fe}_{2}mathrm{O}_{3}$ nanoparticles doping by various concentration of isostructure $mathrm{Cr}_{2} mathrm{O}_{3}$ . Nanoparticles are prepared by sol-gel method, and it was found to stabilize in hexagonal crystal structure with R-3C space group. The room temperature, band gap studies have shown narrowing of the band gap 2.1 eV to 1.75 eV. Compared to pure antiferromagnetic $alpha-mathrm{Fe}_{2}mathrm{O}_{3}$ nanoparticles, ferromagnetism is significantly observed the doped $alpha-mathrm{Fe}_{2}mathrm{O}_{3}$ . Our results improve the understanding of the structural, optical and magnetic properties of Cr doped $alpha - mathrm{Fe}2mathrm{O}_{3}$ as a potential candidate for spintronic applications." @default.
