Title: Magnetovolume effect in Nd{sub 5}Fe{sub 17}

Abstract

The effect of volume expansion on the magnetic properties of Nd{sub 5}Fe{sub 17} is explored using first-principle electronic structure calculations. A volume expansion of 6% increases the magnetization by {approx}6% and the average total exchange parameter by {approx}34%. As a result, the Curie temperature (T{sub C}) is expected to increase from 509 to 682 K. Therefore, some nonhybridizing interstitial and substitutional impurities should produce a moderate increase in T{sub C} of Nd{sub 5}Fe{sub 17}. The possible interstitial sites are discussed.
