Abstract
We have constructed ferroelectric and/or ferromagnetic superlattices by a l ayer-by-layer successive deposition technique with a laser MBE. An ideal he tero-epitaxy can be obtained due to the similar crystal structure of the pe rovskite type ferroelectric BaTiO3, SrTiO3, Bi-based layered compounds and ferro- or antiferromagnetic LaFeO3, LaCrO3, (La,Sr)MnO3. In both superlatti ces, strain effect plays an important role for deterring their physical pro perties. In the Bi-based layer structured superlattices, we have controlled dielectric constant and ferroelectric properties. We also control the spin order on LaFeO3/LaCrO3 superlattices formed on SrTiO3(111) and (100) subst rate. Such a spin structure(ferromagnetic order) cannot be realized in bulk samples.
