Mössbauer effect study of Li21+Me4+Fe63+O122−spinels
(
Baltzer Science Publishers, Baarn/Kluwer Academic Publishers
, 1986 , Article)
Mossbauer effect spectra are obtained for the cubic ferrites Li2 Me Fe6 O12 (where Me4+ is one of the tetravalent elements Ge, Si and Ti) at 78K up to their magnetic transition temperatures. In a rather large temperature ...
The Influence of Cation Substitution on the Magnetic Behaviour of Magnesium Ferrite
(
WILEY-VCH Verlag GmbH & Co.
, 1989 , Article)
New polycrystalline specimens of the ferrites Mg1.5Fe1Si0.5O4, Mg1.5Fe1Ge0.5O4, Mg1.5Fe1Ti0.5O4 and Mg1.66Fe1Sb0.33O4 have been prepared and studied by nuclear gamma ray resonance technique, over a wide temperature range. ...
Mössbauer study of ZnxNi5/3−xFe1Sb1/3O4 spinel ferrite
(
Springer Verlag
, 1985 , Article)
The antimony substituted nickel ferrite ZnxNi5/3–xFe1Sb1/3O4 with different values ofx are prepared, checked by x-ray and studied with57Fe Mössbauer spectroscopy over a wide temperature range. Characteristic spectra of ...
On the Valence State of Iron in Sr0.52+Ca0.52+Fe0.54+ Me0.54+O32−
(
WILEY-VCH Verlag GmbH & Co.
, 1989 , Article)
Powder samples of Sr0.5Ca0.5Fe0.5Me0.5O3 (Me = Co, Zr or Mn) and Sr0.3La0.7FeO3 are investigated by X-ray diffraction and Mossbauer effect spectroscopy.
Analysis of the completely ordered spectra suggested three kinds ...
Absolute evaluation of ferrous and ferric concentration in Ca amphibole
(
WILEY-VCH Verlag
, 1982 , Article)
Studies are made of M?sshauer absorption of 57Fe in a Ca-amphibole schist sample at room and liquid nitrogen temperatures. The absolute concentration and the recoilless fraction for ferrous and ferric cations are determined ...
