I think you guys are overlooking the most obvious flaw, in that a "superferrofluid" should be impossible to manufacture, as a "ferrofluid" by definition must have some amount of intermolecular bonding, where as a "superfluid" cannot have any at all.

Yes, that's what I was about to write: a “superconducting ferro-superfluid” is, as I understand it, an oxymoronic self-contradiction.
