The experimental results, band structure calculations, and theoretical investigations carried
out within the framework of the many-electron models of half-metallic ferromagnets (HMFs) …

The band structure theory of magnetism in 3d-4f compounds is reviewed. Among the open-
shell electrons, a hierarchy of interactions is present which governs the intrinsic magnetic …

Nitrogen enters 3d metals and 3d–4f intermetallic compounds as an interstitial provoking a
dilation of the lattice. Iron-based alloys are most susceptible to modification by nitrogen …

Effects of nitrogen content on crystal structure and magnetic properties have been
investigated in Sm/sub 2/Fe/sub 17/N/sub x/. Sm/sub 2/Fe/sub 17/N/sub x/specimens with 0< …

Permanent magnets are indispensable in modern life and their role in today's technology is
still growing. They form the components of many electromechanical and electronic devices …

The book includes all main physical properties of d-and f-transition-metal systems and
corresponding theoretical concepts. Special attention is paid to the theory of magnetism and …

Abstract Ce 2 Fe 17 N 3–δ composites have always been focused on electromagnetic wave
(EMW) absorbing field because of their high resonance frequency and magnetic loss …

Publisher Summary This chapter describes the interstitially modified intermetallics of rare
earth and 3D elements. The discovery that metastable intermetallic compounds can be …

Iron-rich ternary intermetallics RFe 11 Ti (R= Ce, Pr and Nd) with a ThMn 12-type structure
and their nitrides RFe 11 TiN x (x≈ 1.5) were carefully prepared. After characterizing them …

Mössbauer spectra of Sm 2 Fe 17 and Sm 2 Fe 17 N y in a temperature range between 77 K
and the Curie temperature have been studied. The exchange integrals, as a function of the …
