Outline of Final Research Achievements

Ferroelectric probe data storage has been known as a promising recording technology, because it is a potential candidate to replace the existing magnetic recording. In this research project, we performed a fundamental study and equipment development towards energy-assisted ferroelectric recording to reduce the energetic barrier height of polarization reversal by introducing external energy. We designed a recording head that can be integrated with scanning nonlinear dielectric microscopy (SNDM). In addition, we studied feedback mechanism to systematically identify the voltage necessary for the formation of nanodomains. We theoretically discuss the features of this feedback mechanism and also implemented it to an actual SNDM.
