Need material on anisotropic conductivity

[Troels]

I've stumbled upon a problem whilst doing my master thesis

The problem is to construct the anisotropic conductivity tensor for a material that exhibits Anisotropic magnetoresistance. The problem has left me quite baffled, and coming to think of it, I've never seen a proper treatment of anisotropic conductivity in any of my textbooks or lecture notes.

Well, that only proves that my collection of textbooks is incomplete. Can anyone recommend some good material on the topic?

(Please don't give the solution if you know it, I'd like to have a go at it myself)

Thanks

The first thing I'd look at is Nye's http://books.google.com/books?id=ugwql-uVB44C".
