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

Question

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

Answer 1

Well an electro magnet remains powered due to zero resistance

Answer 2

Yes, but...

although this is simple in principle as all the spins in the ground (0K) state should be aligned, you can get quantised spin waves travelling through the system. The reference below rather avoids the question by showing "complex behaviour" for a ferromagnetic below a certain temperature. You should really read this in detail!

Answer 3

Yes.

Bose condensation has nothing to do with all this.
