N2  - The Mn - Cr ferrite doped with some rare earth is investigated to probe its compatibility as an optical detector The prepared sample has the general formula MnCrxRyFe2 - x - yO4 , where R is the rare earth metal ion R = \\\{Gd , Sm , Ce , Dy and La\\\} IR and X - ray spectra of the prepared samples have been carried out to confirm spinel structure formation
