Phys. Rev. Lett. 92, 187002 (2004) [4 pages]Hydrogen Dominant Metallic Alloys: High Temperature Superconductors?Received 29 December 2003; published 6 May 2004 The arguments suggesting that metallic hydrogen, either as a monatomic or paired metal, should be a candidate for high temperature superconductivity are shown to apply with comparable weight to alloys of metallic hydrogen where hydrogen is a dominant constituent, for example, in the dense group IVa hydrides. The attainment of metallic states should be well within current capabilities of diamond anvil cells, but at pressures considerably lower than may be necessary for hydrogen. © 2004 The American Physical Society URL:
