attoAFM I
MFM on Co Doped Mn2Sb Single Crystal
Magnetic domain structure in the ferrimagnetic state of Co doped Mn2Sb single
crystal imaged using an attoAFM Ixs Magnetic Force Microscopy (here at 290 K).
The image was taken in constant distance mode with the height above the sam-
ple surface set to 50 nm. The area shown in the figure corresponds to 15µm x
15µm with a size of 800 x 800 pixel.

Piezoresponse Force Image on BFO
This image shows the attocube logo electrically written into a BaFeO 3 substrate next
to natural domains of the sample. The data were taken at 4K in piezoresponse force
mode using an attoAFM/MFM I. Image size is 5x5µm².

Local Conductivity Mapping and PFM on BFO Thin Film
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 per-
formed. During the writing phase, a DC voltage of -10 V was applied to write a box.
During the reading, a 5 V pp 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).
