Preparation and comprehensive Characterization of Barium Hexaferrite and Cobalt Ferrite Nono-Wires Embedded in Mesoporous Silica Matrix (MCM-41)

The study of highly ordered densely packed arrays of nano-wires in porous membranes is receiving increasing attraction owing to their application in various devices [1-3]. Highly ordered mesoporouse materials like MCM-41 can be used as template to confine conveniently magnetic compounds in a quasi-one-dimensional array because of its particular topology of regular hexagonal parallel channels with usual average diameters of less than 5nm [4].In this work, we comparative studied the structural and magnetic properties of barium hexaferrite, BaFe12O19, and cobalt ferrite, CoFe2O4, nano-wires by modified wet impregnation of MCM-
