Fe57 Mossbauer Study In Cobalt Substituted Magnetite
(
Qatar University
, 1983 , Article)
The Mossbauer effect has been studied in the mixed ferrites CoxFe3_x04 (for x = 0.8, 0.9 and 1) with the spinel structure in the temperature range between 78 and 830K. The composition with x = 1, showed an expected Zeeman ...
Neutron Diffraction And Mossbauer Effect Study On A Mixed Rare Earth Garnet
(
Qatar University

ON THE CRYSTAL AND HYPERFINE PARAMETERS OF THE HEXAGONAL Ba Cax Sr1_xFe4 O8 MONOFERRITES
(
Qatar University
, 1983 , Article)
The alkaline earth monoferrites BaCaxSr1-xFe4O8 with X = 0,0.5and 1, were studied by Mossbauer spectroscopy and neutron diffractometry over a wide range of temperatures (78 - 900 K). The lattice constants were obtained ...
