Intermediate spin state and the B1-B2 transition in ferropericlase at tera-Pascal pressures

Ferropericlase (fp), (Mg\(_{1-x}\)Fe\(_x\))O, the second most abundant mineral in the Earth's lower mantle, is expected to be an essential component of super-Earths' mantles. Here we present an ab initio investigation of the structure and magnetic ground state of fp up to \(\sim\) 3 TPa wi...
