“…The complex magnetic behaviour of the Fe-rich R-Fe intermetallics (with outstanding properties for permanent magnet applications) is a consequence of an interplay of the localized and itinerant character of magnetic moments on R and Fe atoms, respectively [1,2]. Generally, the ferromagnetic (parallel) arrangement of the magnetic R-and Fe-sublattices is observed for light R elements and ferrimagnetic (antiparallel) arrangement for heavy R elements.…”

Results of pressure measurements of thermal expansion, compressibility, magnetization and Curie temperature of rareearth and transition metals intermetallics are presented. A dependence of compressibility in ferro-(ferri-) magnetic state of the intermetallics on Tc, Kf Tc-1, has been discovered. The pronounced Invar-like behaviour of these materials is described and discussed within thermodynamic relations and itinerant d-electron concepts.

“…The authors reported that a novel compound RiFe,Mh7+!5(M=Ti,V,Mo,W) exists in the compositional range from 2-17 to 1-12 and has a hexagonal structure with a periodicity based on 5 folds of the CaCus-type unit cell for a-and c-directions(l). Hong-Shou Li et al reported RiFe,Mh9 as a stoichiometric compound with monoclinic structure (2). In this study, crystal structure and magnetic anisotropy of SmiFe,V)17+ 0 were investigated using TEM, XRD and Rietveld analysis.…”

The crystal structure and magnetic anisotropy of Sm2(Fe,V) 17+ <5' which is one of the novel compounds identified as RiFe,M)17+ <5 (M=Ti,V ,Mo,W) by the authors, were investigated. The structure type of Sm 2 (Fe,V)17+ <5 was determined by electron diffraction and Rietveld analysis of XRD data. Sm 2 (Fe,Vh7+!5 has a monoclinic structure with the space group P2 1 /c. the same as Nd3(Fe,Tih9' and with a periodicity based on 5 folds of the CaCus-type unit cell. The lattice parameters are a=I.056nm, b=0.852nm, c=0.969nm, {3 =96.82° . The unit cell of this compound has 4e and 2a rare earth sites, which are equivalent to 6c site in Th 2 Zn 17 structure and 2a site in ThMn12 structure, respectively. The easy direction for magnetization of Sm 2 (Fe,V)17+<5 is on the (102) plane, which coincides with the c-plane of CaCu s . This anisotropy can be mainly governed by the local anisotropy of 4e site rare earth.

“…Although NdFe12N decomposes above about 600 ºC, suggesting that conventional thermal processes cannot be applied on this compound to fully densify powders or to develop heat treatment processes for development of coercivity, the excellent magnetic properties at high temperatures are strongly attractive. Finally, it should be mentioned that the ThMn12-type R-Fe compound is a member of homologous compounds Rm-nT5m+2n where T stands for 3d-transition metals 52) .…”

The current status of R&D activities and major results are briefly reviewed, mainly focusing on work reported since about 2010. Developments in and perspectives on less-Dy and Dy-free Nd-(Dy)-Fe-B-type permanent magnets, search and discovery of new hard magnetic materials, progress in the basic understandings of coercivity in hard magnets, and perspectives on anisotropic nanocomposite permanent magnets are overviewed.
