Abstract

We have constructed artificial superlattices with a combination of magnetic/magnetic and ferroelectric/ferromagnetic materials using a laser ablation technique. An ideal hetero-epitaxy can be obtained due to the similar crystal structure of the perovskite type di/ferroelectric BaTiO₃, Pb(Zr,Ti)O₃ (so-called PZT), SrTiO₃ and ferro/antiferromagnetic LaFeO₃, LaCrO₃, (La,Sr)MnO₃. First of all, we have controlled ferromagnetic order on LaFeO₃/LaCrO₃ superlattices formed on SrTiO₃(111) substrate. Such a spin structure (ferromagnetic order) can't be got in bulk condition. In the heterostructured ferromagnetic/ferroelectric devices, (La,Sr)MnO₃/PZT there are remarkable and interesting phenomena. The electric properties of the ferromagnetic material can be controlled by the piezoelectric effect via distortion of the crystal structure.
