I'm a layman so the following terms are not to be taken to the first degree.
I'm searching for a material that offers preferential permeability to magnetic fields. In the article I read (and subsequently lost) the material is offered as an alternative to a Faraday cage in that it doesn't prevent EM fields from entering the cage and the object it protects, but rather encloses the object in a solid shell that forces the fields to flow through the shell - following it's contours - rather than piercing it, for lack of a better term.
Ring a bell, anyone?
