Local Conductivity Mapping and PFM on BFO Thin Film
2 µm
In this application, the versatility of the attoAFM I was demonstrated on
an ultra-thin film of BFO. A simple box writing and reading measurements
was performed. During the writing phase, a DC voltage of -10 V was applied
to write a box. During the reading, a 5 Vpp AC excitation at ~42 kHz on top
of a -2 V DC voltage was used. Using both AC and DC voltage at the same
time allows for a simultaneous measurement of PFM (right image) and local
conductivity (left image).

Piezo Response Force image on BFO
This image shows the attocube logo electrically written into a BaFeO3 substrate next to natural domains of the sample. The data were taken at 4K in
piezo response force mode using an attoAFM/MFM I. Image size is 5x5µm².
