Simultaneous conversion electron, conversion X-ray and transmission Mössbauer spectroscopy

Changes in the hyperfine interactions in the Fe80Nb3Cu1B16 metallic glass under tensile loading

“…The information about the hyperfine interactions of the Mössbauer probe in the investigated material can be extracted from spectra measured in various geometrical arrangements. The Mössbauer spectroscopy in transmission geometry yields information concerning the bulk of a sample; in scattering geometry it allows studying the surface structure up to 30 mm in depth using backscattered g-rays or close surface properties up to approximately 200 nm thick surface layers using backscattered conversion electrons [16]. The use of Mössbauer spectroscopy for observation of the volume changes in solids is known, e.g., from high pressure experiments of crystalline and amorphous solids [17][18][19][20].…”

Interfacial Fe(III)-hydroxide formation during Fe–Pt alloy deposition

“…Velocity calibration was performed at room temperature with a 25 m ␣-Fe foil, and all isomer shifts are related to the latter. The information depth of CEMS is about 150 nm [12]. The amount of Fe 2+ in the electrolyte has been determined by spectrophotometry using o-phenanthrolin that forms an orangered complex with Fe 2+ (E max at λ = 510 nm).…”

“…The conversion and Auger electrons were detected in a He/CH 4 gas-flow proportional counter. The spectra were stored in a multichannel scaler with 1024 channels and fitted according to a least squares fit routine by superimposing Lorentzian lines [12]. Velocity calibration was performed at room temperature with a 25 m ␣-Fe foil, and all isomer shifts are related to the latter.…”

Nitrided Amorphous Stainless Steel Coatings Deposited by Reactive Magnetron Sputtering from an Austenitic Stainless Steel Target

“…[14][15][16] The electrons were detected in a He/ CH 4 flow proportional counter. [17][18][19] The spectra were fitted by a hyperfine field distribution calculated with the Normos code [20] or by superimposing Lorentzian lines with the WinISO fitting tool.…”
