We report a comprehensive angle-resolved photoemission spectroscopy study of NaFeAs, a
prototypical parent compound of the Fe-based superconductors. By mechanically …

We report results of 57 Fe Mössbauer and 31 P NMR studies of a phosphide FeP powder
sample performed in a wide temperature range including the point (TN≈ 120 K) of magnetic …

Muon spin rotation and relaxation studies have been performed on a “111” family of iron-
based superconductors, NaFe 1− x Ni x As, using single crystalline samples with Ni …

Single crystals of Na 1− δ Fe 1− x T x As with T= Co, Rh have been grown using a self-flux
technique. The crystals were thoroughly characterized by powder x-ray diffraction, magnetic …

Single crystals of Na 1− δ (Fe 1− x T x) As with T= Pd, Ni, Cr, and Mn were investigated by
magnetic susceptibility, specific heat, and electronic transport measurements. The structural …

История разработки россыпных месторождений России насчитывает уже 200 лет.
Первое крупное научное обобщение по россыпям связывают с именем ЮА Билибина и …

Abstract 57 Fe Mössbauer spectra were measured at different temperatures between 5.9 K
and 300 K on the recently discovered self-doped superconducting RbGd 2 Fe 4 As 4 O 2 …

Electrical transport measurements are used to study the Rh-doped NaFeAs superconductor
series with a focus on the tetragonal phase. The resistivity curvature has an anomalous …

Fe32+ δGe33As2 and Fe32+ δ′ Ge35− xPx are quasi-binary intermetallic compounds that
possess a rare variant of intergrowth-type crystal structure, which is a combination of the …

In the current work, we report the investigation of RbLn 2 Fe 4 As 4 O 2 (Ln= = Tb, Dy, and
Ho) and RbFe 2 As 2 by 57 ^57 Fe Mössbauer spectroscopy. Singlet pattern has been …
