Submission A new kind of metal theorized to be in the earth's->

slew writes: This article talks about a study accepted to Physical Review Letters that theorizes that Iron oxide goes through an insulator/metal phase change with high temperature and pressure. Originally it was thought to be a crystalline structure change, but now apparently it is theorized to be a new type of metallic state. This discovery might offer new insight on how the earth's magnetic field operates.
