Outline of Final Research Achievements |
Crystalline and porous NiFe2O4 fibers, bulks and thin films were developed to investigate their electronic and magnetic property changes upon organic molecule adsorption. In NiFe2O4 porous bulks, the amount of butyl acetate to induce an electric resistivity change more than one order of magnitude is 1200ul. In NiFe2O4 porous thin films, formic acid adsorption causes 18.4% of magnetization change. These electric and magnetic property changes are caused by a field effect from adsorpted molecules on NiFe2O4 grains to change the amount of carriers and the direction of spins.
