Abstract: | Multiferroic NiFe2O4--BaTiO3 (BTO) bilayeredthin films are epitaxially grown on (001) Nb-doped SrTiOmagnetoelectric effect,epitaxial heterostructure, nickel ferrite, multiferroicsProject supported by the State KeyDevelopment Program for Basic Research of China (Grant No2002CB613303) and the National High Technology Research andDevelopment Program for Advanced Materials of China (Grant No2006AA03Z101) and the National Natural Science Foundation of China(Grant Nos 10574078 and 50621201).7580, 8115I, 6865Multiferroic NiFe2O4--BaTiO3 (BTO) bilayeredthin films are epitaxially grown on (001) Nb-doped SrTiOmagnetoelectric effect,epitaxial heterostructure, nickel ferrite, multiferroicsProject supported by the State KeyDevelopment Program for Basic Research of China (Grant No2002CB613303) and the National High Technology Research andDevelopment Program for Advanced Materials of China (Grant No2006AA03Z101) and the National Natural Science Foundation of China(Grant Nos 10574078 and 50621201).7580, 8115I, 6865Multiferroic NiFe2O4--BaTiO3 (BTO) bilayeredthin films are epitaxially grown on (001) Nb-doped SrTiOmagnetoelectric effect,epitaxial heterostructure, nickel ferrite, multiferroicsProject supported by the State KeyDevelopment Program for Basic Research of China (Grant No2002CB613303) and the National High Technology Research andDevelopment Program for Advanced Materials of China (Grant No2006AA03Z101) and the National Natural Science Foundation of China(Grant Nos 10574078 and 50621201).7580, 8115I, 6865Multiferroic NiFe2O4--BaTiO3 (BTO) bilayeredthin films are epitaxially grown on (001) Nb-doped SrTiO$_{3}$ (STO)substrates by pulsed-laser deposition (PLD). Different growthsequences of NFO and BTO on the substrate yield two kinds ofepitaxial heterostructures with (001)-orientation, i.e.(001)-NFO/(001)-BTO/substrate and (001)-BTO/(001)-NFO/substrate.Microstructure studies from x-ray diffraction (XRD) and electronmicroscopies show differences between these two heterostructures,which result in different multiferroic behaviours. Theheterostructured composite films exhibit good coexistence of bothferroelectric and ferromagnetic properties, in particular, obviousmagnetoelectric (ME) effect on coupling response. |
