A Companhia de Ferro Ligas da Bahia – Ferbasa é a maior extratora do mineral cromita no país e produz 108.000 t/ano concentrados. usina beneficiamento via úmida produziu cerca 3,5 milhões toneladas rejeito, contendo um teor médio 8,5% Cr2O3 (Caetano, 2022). Os resultados mostram que o rejeito minério cromo apresenta 9 fases minerais uma liberação significativa na malha 45 µm, os testes em escal...

Two-dimensional electron gas is precisely confined at the interface of insulating oxide thin films and substrates, e.g., LaAlO3/SrTiO3(STO) and, thus, shows 2D electronic transport features. Here, we report a high mobility state Cr2O3 film STO substrate, which realized by depositing Cr onto (111) substrate in vacuum (1 × 10−10 mbar) using molecular beam epitaxy. At temperature 700 °C, deposited...

Chromium oxide (Cr2O3) doped ZnO nanoparticles were prepared by pulsed laser deposition (PLD) technique at different concentration ratios (0, 3, 5, 7 and 9 wt %) of on glass substrate. The effects dopant the average crystallite size synthesized was examined By X-ray diffraction. morphological features detected using atomic force microscopy (AFM). optical band gap value observed to range between...

Magnetoelectric (ME) effect is a result of the interplay between magnetism and electric field now, it regarded as principle that can be applied to technique controlling antiferromagnetic (AFM) domain state. The ME-controlled AFM state read out by magnetization adjacent ferromagnetic layer coupled with ME via exchange bias. In this technique, reduction in thickness an ongoing challenge. paper, w...
