Using x-ray emission spectroscopy, we find appreciable local magnetic momentsuntil 30-40 GPa in the high-pressure phase of iron, however no magnetic orderis detected with neutron powder diffraction down to 1.8 K contrary to previouspredictions. Our first-principles calculations reveal a "spin-smectic" statelower in energy than previous results. This state forms antiferromagneticbilayers separated by null spin bilayers, which allows a complete relaxation ofthe inherent frustration of antiferromagnetism on a hexagonal close-packedlattice. The magnetic bilayers are likely orientationally disordered, owing tothe soft interlayer excitations and the near-degeneracy with other smecticphases. This possible lack of long-range correlation agrees with the nullresults from neutron powder diffraction. An orientationally-disordered,spin-smectic state resolves previously perceived contradictions in highpressure iron and could be integral to explaining its puzzlingsuperconductivity.
