Formation of ferromagnetic/ferroelectric superlattices by a laser MBE and their electric and magnetic properties
- Osaka Univ., Ibaraki, Osaka (Japan)
The authors 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 BaTiO{sub 3}, Pb(Zr,Ti)O{sub 3} (so-called PZT), SrTiO{sub 3} and ferro/antiferromagnetic LaFeO{sub 3}, LaCrO{sub 3}, (La,Sr)MnO{sub 3}. First of all, they have controlled ferromagnetic order on LaFeO{sub 3}/LaCrO{sub 3} superlattices formed on SrTiO{sub 3}(111) substrate. Such a spin structure (ferromagnetic order) can`t be got in bulk condition. In the heterostructured ferromagnetic/ferroelectric devices,e (La,Sr)MnO{sub 3}/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.
