In 2001 superconductivity with a high critical temperature of 39 K was discovered in MgB2, but efforts since then to identify other diboride-family superconductors have been mostly unsuccessful. Here, the authors report the discovery of superconducti

High-pressure powder neutron diffraction of wustite-Fe0.93O has been achieved to 12 GPa using a large gem-moissanite (SiC) anvil cell. The moissanite anvils are weakly absorbing and provide greater neutron fluxes to the sample than is possible with t

At low pressures the ortho-para conversion in H2 and D2 is a slow process governed by the magnetic dipole interaction of the nuclear magnetic moments, phonons being the main energy sink. As the pressure is raised to a few GPa and the Debye temperatur
