<nmz787>
any ideas on how to clean magnetic particles from a metal "wafer"?
<nmz787>
I am thinking sonication with a magnet taped to the side of the beaker holding my sample

nmz787, what are the magnetic properties of the wafer itself?
<mrdata>
might be a significant factor
<nmz787>
mrdata: it's literally just nickel, came from nickel sulphamate electroforming
<SpeedEvil>
you mean the contaminent, or the wafer?
<nmz787>
the wafer is nickel
<nmz787>
the process was, e-beam lithography on a resist coated wafer, then sputter a metal seed layer, then electroform a thick backing, then peel that off the resist, and dunk it into resist stripper... thus yielding a metal copy of the e-beam features

nmz787, so the magnetic particles hanging on are, what?
<nmz787>
mrdata: no idea, maybe just dirt from the environment... magenetite is a "dirt particle"... whatever might be found when you shove a magnet into some soil/dirt outside (i.e. stuff that can become dust)
<mrdata>
nmz787, is there a way to degauss the stuff maybe?

Hm if you know that it is magnetite, maybe it could be dissolved?
