Local structure of amorphous and crystalline Ge2Sb2Te5 films

Physics of Complex Systems, 2021
An effective way to examine structural rearrangement in solids is Mössbauer spectroscopy. A key requirement to Mössbauer probes used for these purposes is the possibility of their localization in a certain site of the crystal lattice or in the structural

Magnetoresistance Effects in SrFeO(3-x): Dependence on Phase Composition and Relation to Magnetic and Charge Order

, 2005
Single crystals of iron(IV) rich oxides SrFeO(3-x) with controlled oxygen content have been studied by Moessbauer spectroscopy, magnetometry, magnetotransport measurements, Raman spectroscopy, and infrared ellipsometry in order to relate the large ...

Synthesis and Characterization of Unusual S=1 Fe(0)‐Silyl Complexes Supported by Styrene Ligands

Angewandte Chemie, EarlyView.
Despite the long‐standing importance of iron‐silicon bonds as related to catalysis, high‐spin Fe(0)‐silyl complexes remain a historical synthetic challenge in the field. Herein, we report the first series of high‐spin S = 1, styrene‐stabilized Fe(0)‐silyl complexes followed by extensive characterization via Mössbauer spectroscopy, single crystal X‐ray ...

Low‐Temperature Reverse Water–Gas Shift Enabled by Magnetically Induced Catalysis

Angewandte Chemie, EarlyView.
Magnetically induced catalysis using standard Cu–Al spinel‐derived catalyst functionalized with carbon‐coated iron nanoparticles enables high CO yield (up to 62%) at mild catalyst and reactor temperatures (estimated at 300°C and determined as 25–123°C, respectively).

Proximity Engineering of Fe‒N4 Twins for Oriented Generation of Singlet Oxygen for Hospital Wastewater Treatment

Angewandte Chemie, EarlyView.
Precise modulation of Fe–N4 site distances constructs spin‐regulated Fe–N4 twins, triggering a volcano‐type Fenton‐like activity and promoting oriented singlet oxygen generation. The twin‐site catalyst enables highly selective and efficient hospital wastewater purification with simultaneous pharmaceutical degradation and disinfection under low ...

Identification of iron-bearing minerals in basalts and pillow lavas of the Kaczawa Mountains using 57Fe Mössbauer spectroscopy

Nukleonika, 2017
The Kaczawa Mountains along with the Kaczawa foothill comprise a complicated geological unit that is called the Kaczawa metamorphic (Sudetes, SW Poland). The aim of our work was to identify the iron-bearing minerals in samples of basalts and pillow lavas

Moessbauer and magnetic measurements of superconducting LiFeP

, 2010
The LiFeP sample has been prepared by means of high-temperature solid state reaction. A transition temperature to the superconducting state was found as about 5.5 K by measurements of magnetization versus temperature.
