Electronic band structure and properties of the solid solution Eu1–x Fe x O

Europium monoxide as a basis for creating a high-temperature spin injector in the semiconductor spintronics

“…For a possible theoretical justification and understanding of the behavior of the experimental parameters of the EuO : Fe composite, the electronic band structure of the Eu 1-x Fe x O solid solution (SS) structurally included in its composition was calculated in comparison with the same calculation for "pure" europium monoxide [28]. As before, the calculation method included the use of the linear method of associated plane waves (FLAPW, code WIEN2k) with the generalized gradient approximation (GGA) of the exchange-correlation potential [29].…”

“…In calculating [28] the concentration of iron doping of europium monoxide was 6.25% and 12.5%. In the original crystal, a NaCl cubic type cell of EuO consists of the same-named cations of the f-metal (Eu 2+ ).…”

Europium monoxide as a basis for creating a high-temperature spin injector in the semiconductor spintronics

“…The presence of such a transfer, which can be interpreted as the transition of a part of the europium ions Eu 2+ to the Eu 3+ state, and some iron ions to the Fe + state, does not contradict the results of calculations of the electronic band structure of the solid solution, although they do not directly follow from them. To clarify this not-so-obvious fact in [28] on an enlarged scale, the density of electronic states near the Fermi level of SS is given for a composition with 12.5 at.% iron.…”

ON THE CHEMICAL STABILITY OF THE STRUCTURE AND PHYSICAL CHARACTERISTICS OF THE HIGH-TEMPERATURE SPINTRONIC COMPOSITE EuO:Fe UNDER NORMAL CONDITIONS

“…For a possible theoretical justification and understanding of the regularities behavior of the EuO:Fe composite experimental parameters, a model calculation of the electronic band structure of the Eu 1-x Fe x O solid solution, which is structurally included at the composite composition, was performed [10]. The calculation method included the use of the linear method of associated plane waves (FLAPW, code WIEN2k) with the generalized gradient approximation (GGA) of the exchange-correlation potential [11].…”
