Testing the influence of acceleration on time dilation using a rotating MÖssbauer absorber
Y. Friedman, J. M. Steiner, S. Livshitz +10
The aim of the experiment series was to test the influence of acceleration on time dilation by measuring the relative spectral shift between the resonance spectra of a rotating Mos…
Anomalous Eu Valence State and Superconductivity in Undoped Eu3Bi2S4F4
Hui-Fei Zhai, Pan Zhang, Si-Qi Wu +13
We have synthesized a novel europium bismuth sulfofluoride, Eu3Bi2S4F4, by solid-state reactions in sealed evacuated quartz ampoules. The compound crystallizes in a tetragonal latt…
Testing Einstein's time dilation under acceleration using Mössbauer spectroscopy
Yaakov Friedman, Israel Nowik
The Einstein time dilation formula was tested in several experiments. Many trials have been made to measure the transverse second order Doppler shift by Mössbauer spectroscopy usin…
Self doping effect and successive magnetic transitions in superconducting SrVFeAsO
Guanghan Cao, Zhifeng Ma, Cao Wang +14
We have studied a quinary Fe-based superconductor SrVFeAsO by the measurements of x-ray diffraction, x-ray absorption, Mössbauer spectrum, resistivity, magnetization and sp…
Large decrease in the critical temperature of superconducting LaFeAsO0.85 compounds doped with 3% atomic weight of nonmagnetic Zn impurities
Y. F. Guo, Y. G. Shi, S. Yu +10
We observed a large decrease of Tc by no more than 3 at.% of Zn doped to the optimized superconductor LaFeAsO0.85 (Tc = 26 K), confirmed by measurements of electrical resistivity,…
Mossbauer Spectroscopy Determination of iron foreign phases in the Superconducting Systems; RAsFeO1-x, RAsFeO1-xFx and Sr1-xKxFe2As2
I. Nowik, I. Felner
The recently discovered superconducting - spin density wave materials, containing Fe and As, have raised huge interest. However most materials prepared to date, suffer from a varyi…
