To Study the Effect of Magnetic Dipoles on the Atomic Parameters of Diamagnetic, Paramagnetic, and Ferromagnetic Compounds at Their K, L, and M Shell Absorption Edges
摘要
The effect of a magnetic dipole on atomic parameter jump factor (JK, JL, and JM), jump ratio (rK, rL, and rM), effective atomic number (Zeff), linear attenuation coefficient (μL), and Davisson-Kirchner ratio (D) of diamagnetic (C6H6, C3F6O, CaF2, CCl4, H2O, NaCl, CHCl3, SiO2, ZnSO4, AgCl), paramagnetic (NO2, FeBr2, FeSO4, MnO2, CuSO4, FeCl2, MnCl2, CoCl2, CuCl2, FeO), and ferromagnetic compounds (BaFe12O19, CrO2, Fe2N, ZnFe2O4, Fe3O4, MgFe2O4, SmCo5, NiFe2O4, CoFe2O4, Eu2O4) has been calculated at the K, L, M shells absorption edges. We observed irregularities in atomic parameters (JK, rK, JL, rL, JM, rM, Zeff, μL, and D) at the absorption edges of K shell, L shell, and M shell in diamagnetic, paramagnetic, and ferromagnetic compounds at different incident energies. FFAST was used to calculate the values of their atomic parameters. From the obtained results, it has been observed that ferromagnetic compounds show maximum variations in atomic parameters as compared to diamagnetic and paramagnetic compounds. We observed maximum value for μL is 7692.961, μL is 18302.462, and μL is 21652.463 for ferromagnetic compounds (BaFe12O19, SmCo5, and Eu2O3). Maximum peak value for rK is 27.271, rL is 8.087, and rM is 1.634 for ferromagnetic compound (SmCO5) and the maximum peak values for JK is 5.756, JL is 75.933 for C6H6, and JM is 124 for SiO4 magnetic compounds respectively. As we observed a wide variation in atomic parameters of diamagnetic, paramagnetic, and ferromagnetic compounds, the exact knowledge of atomic parameters is an important task before using these compounds in industrial, medical, and scientific domains.
