From PhysicsWorld last year:
One of the most promising and well backed seems to be iron nitride (FeN). Based on just two materials β iron and nitrogen β that are cheap and in plentiful supply, it has a BHmax of 1150 kJ/m3 and a Tc of 540 oC. Firms like Niron in Minnesota, US, are already investing substantially in the area, employing a large and growing number of materials scientists to fine-tune its properties and production.
