Abstract
Starting from band structure calculations and 4f–5d–3d exchange interaction model, the magnetic properties of [Formula: see text], [Formula: see text], [Formula: see text] and both rhombohedral and hexagonal [Formula: see text] series are analyzed. The complex and interdependent exchange interactions, within the spatial extent of the unit cell, are mediated by the R5d band polarizations, [Formula: see text]. The Curie temperatures of the analyzed series show linear dependences, with the same rate for both light and heavy rare-earth compounds, when plotting as function of [Formula: see text] values. The effects of substitutions at R and Co sites are discussed in correlation with changes in R5d band polarizations.
