er control the conditions under which perovskite is synthesized, Grocholski et al. measure the spin state of iron in perovskite. They find the dominant spin state at pressures below 50 gigapascals (7.25 million pounds per square inch) to be high spin but observed a transition to a possible mixed spin state at higher pressures. These results indicate that perovskite is in a mixed or high spin state at least to 2,000 kilometers (1,242 miles) depth in the mantle, consistent with computational results.

Title: Spin and valence states of iron in perovskite
