Does anyone know of a substance that can block a magnetic field?

Look up something called "mu metals".

Caution: there are no practical material (of arbitrary thickness) that can shield magnetic field of arbitrary strength. So your question is rather vague.

I've heard of one, I think it started with an I.

golansha, are you talking about the meissner effect ?

Check the superconductors.
(Not blocking but an interesting effect!)

I've found such an interesting question on this website,
http://www.newton.dep.anl.gov/askasci/phy00/phy00508.htm

It is also very helpful for my little knowledge about the magnetic field. So thanks for the question
