SEM analyses of sample A (a) and sample I (b) on the tape side that is coated with a ferromagnetic material. The first number from the bottom left of both figures is the power of the electrons beam (20 kV); the second is the magnification rate ( 10,000 in (a) and 20,000 in (b)); the third is the scale (the white segment above indicates the proportion, here 1 μm); the progressive number in the analysis session; the sample identification number.
