I'm not sure, and I'm not a geologist, astrophysicist or even a
physicist, but I would argue it is unlikely. The core is believed to
contain not just nickel-iron, but other heavy elements. This suggests
to me that the core cannot form a nice crystal lattice, and likely has
an amorphous structure. But a lot likely depends on the behavior of
this mixture at high pressures and temperatures; things can get rather
counterintuitive down there, so I wouldn't be totally surprised if it

Is there a geologist in the house? :-)
