Abstract: Abstract Magnetic nanoparticles of e-Fe1.76Ga0.24O3 were prepared by thermal treatment of a mesoporous silica matrix impregnated with nitrates. The chosen Ga-doping enhanced magnetization and suppressed the low-temperature spin-reorientation transition typical for e-Fe2O3. Despite the small… read more here.
