Is a permanent magnet still magnetic at absolute zero (Bose Condensates notwithstanding) ? - bose at ellington

Yes, but ...
Although it is simple in principle, all the spins in the ground (0K) state should be aligned, you can receive quantum spin waves propagating in the system. Link below avoids the question, shows a "complex behavior" for a ferromagnet below a certain temperature. You should really read in detail!
