Extended Data Fig. 9: Partial ferroelastic writing along the depth direction examined by ECC imaging.
From: Ferroelastic writing of crystal directions in oxide thin films
a, ECC image of ferroelastic domains written at different loading forces of 3.0, 3.7, and 4.4 μN in a 20 nm-thick SrRuO3 (001) thin film. The white boxes mark the ferroelastically written regions. Red and yellow dotted arrows indicate the fast and slow scan directions. b, To clearly visualize the colour differences in the ECC image, the three regions written with different loading forces in (a) are displayed as 1 × 1 μm2 cropped images. As the loading force increases, gradual increment of the G value in the ECC colour (right panel) suggests increasing switched volume.
