We report neutron scattering and transport measurements on semiconducting Rb 0.8 Fe 1.5
S 2, a compound isostructural and isoelectronic to the well-studied A 0.8 Fe y Se 2 (A= K …

We use neutron scattering to study the spin excitations associated with the stripe
antiferromagnetic order in semiconducting K 0.85 Fe 1.54 Se 2 (TN= 280 K). We show that …

We report on single-crystal growth, stoichiometry, structure and basic characterization of Rb
1− x Fe 2− y Se 2− z S z crystals where Se is substituted by S. The temperature and …

Abstract Series of Fe-site–substituted K 0.8 Fe 1.75− x M x Se 2 (M= Cu, Ni, Mn, Zn, Co, Cr)
single crystals of nominal composition have been prepared and microstructural features …

We have investigated the physical properties of single-crystalline K x Fe 2-y S 2 and K x Fe 2-
y Se 2 samples using 57 Fe Mössbauer spectroscopy. The observed 57 Fe Mössbauer …

The structural and electronic properties of high-quality K0. 66 (6) Fe1. 75 (10) S2 single
crystals have been investigated by angle-resolved X-ray diffraction and 57Fe nuclear …
