Nanocomposites NiFe2O4/SiO2 and CoFe2O4/SiO2-preparation by sol-gel method and physical properties

Abstract

This paper aims to characterise the systems NiFe2O4/SiO2 and CoFe2O4/SiO2 prepared by the sol-gel method. The various samples have been studied by means of X-ray diffraction, Mossbauer spectroscopy, magnetic measurements atc.
