Structural and magnetic properties of pulsed laser deposited SrRuO3/CoFe2O4/La2/3Sr1/3MnO3 magnetic oxide heterostructures on SrTiO3(001) and MgO(001)
We report on the growth of all-oxide SrRuO 3 /CoFe 2 O 4 /La 2/3 Sr 1/3 MnO 3 and La 2/3 Sr 1/3 MnO 3 /CoFe 2 O 4 /SrRuO 3 heterostuctures on SrTiO 3 (001) and MgO(001) substrates by pulsed laser deposition. Structural analyses by X-ray diffraction and transmission electron microscopy clearly indica...

layer is grown first, whereas trilayers with SrRuO

at the bottom are more disordered. Both the substrate material and the deposition sequence strongly influence the formation of various structural defects such as interfacial dislocations and sub-grain structures, and this is clearly reflected by a reduction of the saturation magnetization in the top electrode. When the substrate material and the deposition sequence are correctly chosen, however, the magnetic moments of the La
