Hydrogen constitutes more than 90% of all atoms in the visible universe and most are at extreme conditions. It has been proposed that compressed hydrogen might cross over into a metallic state and eventually become a superconductor with a high transition temperature Tc. Although metallic hydrogen in the solid form has not yet been achieved, the metallic and superconducting states were recently found in hydrogen-rich compounds.
Magnetism and ferroelectricity are essential to many forms of current technology. The multiferroic-based device could provide an efficient link between conventional electronic logic and spin-based logic, which offers the potential for significantly reduced energy consumption compared to present-day integrated circuits. An important number of magnetoelectric multiferroics has the general chemical formula ABO3 and crystallizes in a perovskite or perovskite-related structure.
