Acquisition of multiple hysteresis loops on a closely spaced square grid enables polarization switching parameters to be mapped in real space. Piezoresponse amplitude and phase hysteresis loops show collective symmetric\/asymmetric characteristics, affording information regarding the switching behavior of different domains. As such, the out-of-plane polarization states of the domains, including amplitudes and phases can be determined.*<\/p>\n\n\n\n

The results presented by the authors could contribute to a further understanding of the relationships between polarization switching and polarization vectors at the nanoscale, and provide a feasible method to correlate the polarization hysteresis loops in a domain under an electric field with the polarization vector states.*<\/p>\n\n\n\n

PFM and SS-PFM were implemented on a commercial Atomic Force Microscope using NanoWorld PlatinumIridium coated Pointprobe\u00ae<\/a> EFM <\/a>AFM probes.<\/p>\n\n\n\n
