Conventional permanent magnets composed of niobium, iron and boron became industrially widespread in the 1990s, yet they have resisted significant efforts to improve their performance, said Zhang, an Argonne materials scientist. But the motors in electric and hybrid cars contain approximately a tenth of a kilogram of dysprosium per motor.
