Spin orientation and magnetostriction of Tb1−xDyxFe2 from first principles

The optimal amount of dysprosium in the highly magnetostrictive rare-earth compounds Tb1−xDyxFe2 for room-temperature applications has long been known to be x = 0.73 (Terfenol-D). Here, we derive this value from first principles by calculating the easy magnetization direction and magnetostriction as...
