英文摘要
In this study, tunneling-spin filtering effect of ferromagnetic insulator CoFe_2O_4 with perpendicular magnetic anisotropy was studied. To improvement surface flatness of CoFe_2O_4 films, the films were grown on MgO(001) substrates by pulse laser deposition method with a shadow mask. The CoFe_2O_4 films without droplet formation with perpendicular anisotropy energy density of 2.36x106 erg/cm3 were obtained. Magnetoresistance measurements were carried out for magnetic tunnel junctions (MTJs) using MgO/CoFe_2O_4 and ferromagnetic metal L10-type FePd electrodes fabricated on MgO (001) substrates. The tunnel magnetoresistance ratio of 0.7% at 5 K and 16.5% at 300 K was obtained for the MTJs.
