I think a solid iron/nickel core, surrounded by a molten iron/nickel outer core

Branman... is right. It is a solid core with a liquid mostly iron core surrounding it. I have heard an interesting theory that Uranium is so heavy that it is very concentrated in the core and accounts for much of the heat allowing our planets active geology. It could be there is a nuclear pile or reactor of sorts at the core.

The theory is that there is a mass of solid iron-nickel, as described in some previous answers. No one has actually been there, of course, to confirm this, but the evidence is pretty solid (no pun intended).

Earth's inner core is solid iron, its outer core is liquid iron mixed with other components, and its mantle is dense rock.

Molten iron core, the movement of which generates our magnetic field.
