Sigma-phase in Fe-Cr and Fe-V alloy systems and its physical properties

, 2011
A review is presented on physical properties of the sigma-phase in Fe-Cr and Fe-V alloy systems as revealed both with experimental -- mostly with the Mossbauer spectroscopy -- and theoretical methods.

Elaboration and characterization of Fe1–xO thin films sputter deposited from magnetite target [PDF]

, 2007
Majority of the authors report elaboration of iron oxide thin films by reactive magnetron sputtering from an iron target with Ar–O2 gas mixture. Instead of using the reactive sputtering of a metallic target we report here the preparation of Fe1–xOthin ...

Formation of Cobalt Ferrites Investigated by Transmission and Emission Mössbauer Spectroscopy

Acta Chimica Slovenica, 2020
This study focuses on cobalt and iron ordering within a ferrite structure CoxFe3-xO4, formed during a solid-state reaction of α-Fe2O3 and CoCl2. A unique combination of transmission and emission Mössbauer spectroscopy was employed to inspect selectively ...

57Fe Mossbauer spectroscopy and magnetic measurements of oxygen deficient LaFeAsO

, 2012
We report on the magnetic behavior of oxygen deficient LaFeAsO1-x (x-0.10) compound, prepared by one-step synthesis, which crystallizes in the tetragonal (S.G. P4/nmm) structure at room temperature. Resistivity measurements show a strong anomaly near 150

The Debye temperature of sigma-phase Fe-Mo compounds as determined with M\"ossbauer spectroscopy

, 2012
The Debye temperature, T_D, of sigma-phase Fe_(100-x)Mo_x compounds with 47 < x < 56.7 was determined from the temperature dependence of the centre shift of M\"ossbauer spectra recorded in the temperature range of 80 - 300 K. Its compositional dependence
