Today we're looking at Atomic Force Microscopy! I built a "macro-AFM" to demonstrate the principles of an atomic force microscope, then we look at a real AFM (an nGauge AFM from ICSPI) and do a few ...
(A) a single magnetic domain and (B) multiple magnetic domains with opposite polarization. (C) Following the subtraction of image (A) from image (B), a Kerr image with sharp contrast is obtained [39].
