The magnetic domain structure of garnet film is being reorganized by a cantilever tip with a magnetic coating. The 1300 nm IR laser of the AIST-NT AFM system allows the user to clearly observe the sample during the scanning process. In the meantime, it also points out the fact that the selected cantilever is not suitable for MFM measurement of such magnetic samples.
AIST-NT presents a new application note by the group of Professor Andreas Ruediger at INRS-EMT, University of Quebec (Canada) focusing on high-resolution ferroelectric domain imaging and hysteresis measurement by piezoresponse force microscopy (PFM) with the SmartSPM 1000.
In this phase image, the lower right nanoparticle clearly shows the pentagonal shape. The ability to distinguish the shape of such a small nanoparticle despite significant convolution effect is quite an impressive result.
