Abstract: Much research into understanding how the Earth's iron-rich core formed centres on how nickel and cobalt behave at high temperatures and pressures, and so might have partitioned between the mantle and core early in Earth history. Experiments employing a diamond anvil cell now take this line of research into new territory by reaching pressures of up to 80 gigapascals, equivalent to a depth of about 1,900 km.
