abstract = {Magnetic properties of NiO have been studied in the
multimegabar pressure range by nuclear forward scattering of
synchrotron radiation using the 67.4 keV Mössbauer
transition of Ni61. The observed magnetic hyperfine
splitting confirms the antiferromagnetic state of NiO up to
280 GPa, the highest pressure where magnetism has been
observed so far, in any material. Remarkably, the hyperfine
field increases from 8.47 T at ambient pressure to ∼24 T
at the highest pressure, ruling out the possibility of a
magnetic collapse. A joint x-ray diffraction and extended
x-ray-absorption fine structure investigation reveals that
NiO remains in a distorted sodium chloride structure in the
entire studied pressure range. Ab initio calculations
support the experimental observations, and further indicate
a complete absence of Mott transition in NiO up to at least
280 GPa.},
