Spin orientation and magnetostriction of Tb${}_{1-x}$Dy${}_x$Fe${}_2$ from first principles

Christopher E. Patrick, George A. Marchant, Julie B. Staunton

The optimal amount of dysprosium in the highly magnetostrictive rare-earth compounds Tb${}_{1-x}$Dy${}_x$Fe${}_2$ for room temperature applications has long been known to be $x$=0.73 (Te…
