“…On the other hand, an influence of the M-sublattice on the mentioned properties is known only partially [1][2][3][4][5][6][7]. The ferrimagnetism of these compounds is related to the coexistence of 4f -3d magnetism, which is mediated mainly by the band-type 5d electrons [5,8,9]. Nevertheless, the electronic band structure of these intermetallics and in particular of their transition metal sublattice is complex and poorly understood yet.…”

“…The Mössbauer effect is an especially suitable nuclear method to study separately the R-or M-sublattice of the intermetallics [8,9]. Often, for this purpose the Mössbauer effect ate the 161 Dy and 57 Fe nuclei is used to test the rare earth • and the transition metal sublattice, respectively [8][9][10][11][12].…”

“…Both the magnetic and the Mössbauer effect studies were performed previously for a number of the Ru Mv series [1][2][3][4][5][6][7][8][9][10][11][12]. In order to find the influence of the number of 3d electrons on the R and M magnetism, the pseudobinary R u (M-M)v compounds.…”

“…were studied, where M-M = Mn-Fe, Fe-Co, Co-Ni, etc. [8][9][10][11][12]. The purpose of the paper is to present some literature data related to the 4f -3d magnetism of the Ru (M-M)v intermetallics.…”

Applications of the Mössbauer effect at the 161 Dy and "Fe nuclei to study heavy rare earth -transition metal compounds are presented. Magnetic hyperfine fields at dysprosium and iron nuclei observed in the Dyu (M-M)v intermetallics (u/v = 2/17, 6/23, 1/3, and 1/2; M-M = Mn-Fe, Fe-Co, and Co-Ni), magnetic moments and magnetic ordering temperatures are discussed. The magnetic hyperfine field at iron nuclei and the field at dysprosium nuclei treated as functions of a number of 3d electrons form two different systems of the Slater-Pauling curves. The magnetic ordering temperatures treated as functions of the number of 3d electrons also form the u/v system of curves. Considermg the magnetic data and the magnetic hyperfine fields it can be concluded that intermetallics can be treated as three-subsystem ferrimagnets. Consequently, a coexistence between the 4f, 5d, and 3d magnetism in the rare earth -transition metal compounds can be qualitatively explained.

The synthesis of materials and the studies of crystal structure and 57 Fe Mössbauer effect were performed for Tb0.27Dy0.73(Fe1−xCox)2 intermetallics. Terfenol-D (Tb 0.27Dy0.73Fe2) is the starting compound of this Fe/Co-substituted series. X-ray measurements showed evidence of a pure cubic Laves phase C15, MgCu2-type, and unit cell parameters were determined across the series. A Co substitution introduced local area, at sub-nanoscale, with random Fe/Co neighbourhoods of the 57 Fe atoms.Mössbauer effect spectra for the Tb 0.27Dy0.73(Fe1−xCox)2 series at room temperature are composed of a number of locally originated subspectra due to the random distribution of Fe and Co atoms in the transition metal sublattice, and due to [1 1 1] an easy axis of magnetization. Isomer shift, magnetic hyperfine field and quadrupole interaction parameter were obtained from the spectra, both for the local area and for the bulk sample.As a result of Fe/Co substitution, a Slater-Pauling-type curve for the average magnetic hyperfine field vs. Co content was observed. It was found that the magnetic hyperfine fields corresponding to the local area also create a dependence of the Slater-Pauling-type vs. Co contribution in the Fe/Co neighbourhoods.
