Take a look at the extensive library here:

http://www.mag-inc.com/library.asp

There is a section labled "General Information"
on this page that might provide a start with
some back ground information.

There are also product and material selector
guides that can assit you in selecting suitable
core material for a transformer.

Others may have more specific pointers/advice, but
in the meantime this is my input on this subject!
