Electronic structure and ionic radius. electron probabilities for gadolinium. Electron probabilities, P2(r), for the 4f, 5s, 5p, 5d, and 6s electrons of gadolinium. The chemical, metallurgical, and physical behaviours of the rare earths are governed by the electron configuration of these elements.
To illustrate the electronic structure of rare-earth infinite-layer nickelate, we perform first-principles calculations of LaNi O 2 and NdNi O 2 compounds and compare them with that of CaCu O 2 using the hybrid functional method together with Wannier projection and group symmetry analysis.
1 de ene. de 2016 · Current theoretical understanding of electronic structure and spectroscopy of rare-earth ions in a condensed matter environment is reviewed. The development of the crystal-field effective Hamiltonian for the 4f n configuration, and its extension to the 4f n−1 5d configuration, is discussed.
Because of that compositional simplicity, their properties can be surmised, at least partially, from the location of their constituent atoms in the periodic table. This Quick Study explores the influence of the rare earths’ electronic structure on their properties and applications.
• Use literature and new data for electronic energy levels, magnetic, and hyperfine splitting. • Directional magnetic data is crucial to fixing orientation of CF Hamiltonian for low-symmetry sites. • Separately calculate: • Electronic energy levels • Magnetic splitting for various field orientations • Hyperfine splitting.
1 de feb. de 2019 · Rare earths are characterized by the prevalence of the trivalent oxidation state; however, some electronic configurations stabilize the divalent (Eu II, 4f 7) or the tetravalent (Ce IV, 4f 0) states under ambient conditions.
Hace 5 días · rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 ( scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table ( cerium [Ce] through lutetium [Lu]).
