SnHPO 4 was synthesized by precipitation and characterized by X-ray diffraction. The discharge curve of electrochemical cells using SnHPO 4 as active cathode material and metallic lithium as anode showed a first reduction step at ca. 1.5 V. X-ray dif

125 Te-Mossbauer spectroscopy has been used to verify whether the observed ionic transport crossover for the Ag–As–Se–Te glasses with a silver content of 15 at.% at approximately equimolar Se/Te ratio is accompanied by variations in the hyperfi

The tin reduction during lithium insertion in spinel sulfide compounds is investigated. Mossbauer and RMN spectroscopy are combined with tight binding calculations to analyze the reduction mechanism. It is shown that the formal reaction SnIV + 2e-

The 125 Te Mossbauer spectroscopy of different 1T-transition metal ditellurides shows that the values of the isomer shift are dependent on the degree of the TeTe interlayer interactions which decrease the 5 p population by Te( p )-M( d ) electron

A simple interpretation of 125Te Mossbauer data of solids based on a chemical bonding analysis is presented. From new measurements of the Mossbauer spectra for different compounds a scale of the isomer shifts is obtained. A qualitative analysis of th

CeSb is a cubic trivalent Ce compound. Its very abnormal magnetic diagram contains 16 different phases depending on magnetic field and temperature. These complex physical properties could be interpreted in the framework of the p-f mixing model based

Mossbauer spectroscopy is a very suitable method to study very weak modifications of electronic states in the valence band. It probes the local environment of the central atom. The isomer shift (δ) measures the s electron density on the nucleus and

Cu4In20S32 and In16Sn4S32 spinel compounds are used as cathode material in Li/LiClO4(PC)/sulphide cells. For both compounds, incremental capacity vs. voltage curves and diffusion coefficients vs. composition curves showed two consecutive steps of int
