Magnetic Force Microscope (MFM)

[Received the Magnetic Society of Japan Best Paper Award 2003 & 2005]

A magnetic action between magnetic probe and sample is produced and imaged as potential changes in cantilever oscillation.
High sensitivity and high resolution magnetic domain imaging is possible by measuring in vacuum.
