Ola Virginia,
If you really canīt see that specimen by SEM, I would think that it's
an ideal application for AFM(or maybe even MFM, Magnetic Force
microscopy). AFM can commonly see very low height features which are
hard to spot using SEM. 20 nm height features are certainly no problem,
and it doesn't really matter what the materials are. MFM is a variant,
which allows you to map magnetic fields. However,it's abit more
complicated than AFM, which would probably do the job, anyway. Feel
free to contact me off list if you need more information. I see you are
in portugal, so i may even be able to run the samples for you (if
you're not in a hurry!)
good luck!
pete.
