Abstract

Bismuth-based-layer-structured ferroelectric films have been formed epitaxially on Nb-doped SrTiO₃ substrates by pulsed laser deposition (PLD). These films show an atomically smooth surface with a wide terrace of 100 nm-200 nm, as observed by atomic force microscopy (AFM) which is ideal for measuring such properties. Thin films of (Bi_0.7, Ba_0.3) (Fe_0.7, Ti_0.3)O₃ exhibit both ferroelectric and ferromagnetic (weak ferromagnetism) properties at room temperature. In these samples, a size effect is discussed at the same time.
