The material needs to act as a shield between two magnets to keep them from being attracted to each other. Likewise, they can't be attracted to the shield, either (which rules out Mumetal, Ni, Co, etc.)

I know of no known material that meets all of your criteria.
Any metal that is magnetic will divert the field and greatly weaken the force between the magnets, but the total magnetic attraction will remain the same because of the magnets' attraction to the metal placed between them.
To date, all effective magnetic shields are made from materials which are themselves magnetic.

A superconductor would work best. It not only blocks magnetic fields, it repels them.
