I have a problem with one of my Epsilon L-EMIMs. During transportation one L-EMIM got hit (slightly). As a result, a magnet (one only) detached,scratched the foil (without tearing it!), hit an aside magnet and broke. The foil is dead and needs replacement. A friend of mine is in the etching business and will make me a new one (plus some more for spares), since Infinity doesn't stock them any more. It's a good thing that EPSILON white paper describes exactly how it is made! My real problem is the magnet... It is black,it doesn't corrode on surface,doesn't look to have any coating. I have sources to make me a magnet with the same dimensions but i need to know what type of magnet this is! Is it ceramic (what type?), samarium cobalt or neodymium (again what type N42 N45 etc etc)... Anyone knows any details on the subject or has any "inside" info about this? Wanna be be a lifesaver?
