摘要: Enhancement in coercivity values of precursor powders cobalt ferrite embedded silica xerogel as well polyaniline was observed using vibrating sample magnetometry. We compared the magnetic properties pure prepared by coprecipitation method and those matrix, sol-gel a conventional situ chemical oxidation polymerization, respectively. The main effect is altered value growing two magnitude orders for polyaniline. goes from 52 Oe to 2200 1054 coprecipitated powder xerogel, polyaniline, respectively, without any heat-treatment.
