“…These results complement other analyses that have been performed on the same group of compounds or on particular lanthanide ions [29]; in addition, they pertain to single crystals as well as to powder samples with nanosize of the particles [5, 7; 19, 24]. The present treatment should provoke also a systematic reexamination of the magnetic transition temperatures in the group of OLA.…”

“…Crystal field calculations of magnetic properties in rare-earth systems are usually described within the Steven's formalism of operator equivalents [35,36], however these techniques are insufficient for Sm 3+ as they only consider the ground state J-multiplet. Here we use an extension of the Steven's formalism which allows for the inclusion of higher multiplets [19], derived with the algebraic methods of tensor operators.…”

“…where χ k contain the angular part of the matrix elements, described in Ref. [19] for all the trivalent rare-earth ions. We are then left to determine A 4 r 4 and A 6 r 6 , which can be either treated as adjustable parameters or calculated within, e.g., the point-charge model.…”

“…Amongst the data previously proposed in the literature for the crystal field coefficients in SmCo, (Sankar et al [5], de Wijn et al [6], Boucherle et al [7]), those of de Wijn et al [6] can be markedly better fitted within our one-particle model than the others. Therefrom, we infer that the effective one-particle interatomic forces in SmCo, are of the Born type, in agreement with the general quantum picture of the effect,ive interatomic forces in solids (see Torrens [8] for a comprehensive survey).…”
