Figure 3: Modest magnetic fields induce partially reversible changes in ferroelectric domains.
From: Magnetic switching of ferroelectric domains at room temperature in multiferroic PZTFT
Phase images from lateral piezoresponse force microscopy (LPFM) change depending on the orientation of the magnetic field applied to the PZTFT lamella. Both the images in (a) and the area histograms of different phase colours (b) illustrate that 3 kOe applied in a nominally positive direction, perpendicular to the lamellar surface, favours the growth of polarization directions indicated by red contrast. When applied in a nominally negative direction, these regions contract. Scale bar, 2 μm.
