Abstract

Ferroelectric and mutiferroic materials have been studied from the viewpoint of pure and applied physics. For the applications, a study from the viewpoint of materials science will be important in the future. Examples of materials science study are substitution of elements, selection of substrate in thin films and in-situ observation. Nano-scale domain configurations of multiferroic BiFeO3 thin films and their dynamic response to the externally applied fields have been investigated by piezoresponse force microscopy. High-resolution piezoresponse images reveal that nano-scale domain walls are approximately with ~2 nm in width. In this article, we focus on BiFeO3 as mutiferroic materials and as ferroelectric materials. We will present our results about electric and magnetic properties, and scanning probe microscopy observations. Local polarization reversal and retention behavior will also be presented and discussed.
