 There is no such thing as a "special case" when it come to losses in
magnetic materials. I don't know where you got that from, but it is an
outrageous fairy tale. Since the Fair-Rite catalogue clearly lists and
charts to loss tangent for their materials, including 61, perhaps you would
care to enlighten us as to where this miracululous lossless material (which
defies all manner of physics) came from?
