Measurement of atomic number and mass attenuation coefficient in magnesium ferrite

Abstract

Pure magnesium ferrite sample was prepared by standard ceramic technique and characterized by X-ray diffraction method. XRD pattern revealed that the sample possess single-phase cubic spinel structure. The linear attenuation coefficient (μ), mass attenuation coefficient (μ/ρ), total atomic cross-section (σtot), total electronic cross-section (σ ele ) and the effective atomic number (Z eff ) were calculated for pure magnesium ferrite (MgFe2O4). The values of γ-ray mass attenuation coefficient were obtained using a NaI energy selective scintillation counter with radioactive γ-ray sources having energy 0.36, 0.511, 0.662, 1.17 and 1.28 MeV. The experimentally obtained values of μ/ρ and Z eff agreed fairly well with those obtained theoretically.

Structure and magnetic properties of Co-Zn substituted hexagonal ferrites

“…The hexagonal ferrites as permanent magnets have been used for thousands of years [1] and play an important role in daily-life applications [2][3][4][5][6]. The development of magnetic materials with material derived from mineral minerals has been first described in 1925 and continues in 1938 the hexagonal crystal with the composition PbFe7.5Mn3.5Al0.5Ti0.5O19 [7].…”
