At temperatures of 650 - 800 ° C , we have observed a 2.7 % increase in weight in the TG curve accompanied by an exothermal effect with a maximum at 808 ° C , facts which can be rationalized by the partial oxidation of the sodium ...

This is confirmed by the magnetic susceptibility measurements as well as by the fact that the temperature , at which the hyperfine magnetic splitting appears in the 57Fe Mössbauer spec- tra , coincides with the Neel temperature of ...

This fact was explained by a difference between the electronic configuration of Cr3 + ( 120 ) and Fe3 + ( 12 ) , which are responsible for polarization of Snions , i.e. , by the lack of e , electrons in the Cr3 + ions involved in the ...
