Spin polarization of f bands in RCo5, R2Co17, and R6Mn23 compounds

The d bands for RCo5, R2Co17, and R6Mn23 compounds are formulated by Deegan’s prescription and the formulas of Slater and Koster. The d-f elements for these energy bands derived by Lendi are taken into account. The spin polarization of the f bands are investigated. The obtained result explains the e...

Description
Summary:The d bands for RCo5, R2Co17, and R6Mn23 compounds are formulated by Deegan’s prescription and the formulas of Slater and Koster. The d-f elements for these energy bands derived by Lendi are taken into account. The spin polarization of the f bands are investigated. The obtained result explains the experimental result by taking into account the feeble exchange splitting in 4f bands. Additionally, the magnetic moment of rare earths is calculated on the basis of the band model and the calculated result is compared with gJ. It is found that in these compounds the spin polarization is saturated and the moments are much the same as gJ.
