Proving the existence of high temperature, intermolecular nuclear magnetic ordering in nanoconfined H2
Magnetic nuclear spin correlations between nuclei are very rare in materials, typically only occurring at very low temperatures (nK-mK). These coherent quantum phases of matter are of particular interest as quantum sensors or even as neutron polarizer materials. We have collected preliminary data indicating long-range nuclear spin coupling may occur for nanoconfined hydrogen molecules (H2) at temperatures 3-4 orders of magnitude higher than the current record. Using temperature-dependent XYZ spin polarised neutron scattering on WASP, these experiments will decouple nuclear spin-incoherent, nuclear coherent and magnetic scattering of nanoconfined H2 to experimentally determine if previously observed scattering deviations are indeed caused by intermolecular (H2-H2) nuclear-spin correlations or alternatively originate from nuclear short-range order between H2 and C or electronic magnetic interactions with the carbon network. If nuclear spin correlations between nanoconfined H2 molecules are proven, this work will demonstrate how coherent quantum phases of matter can be generated at temperatures far higher than the current state of the art using a simple methodology ¿ nanoconfinement.
