Nitrogen-induced degradation of Nd sub 2 Fe sub 14 B

Nitrogen-induced degradation of Nd sub 2 Fe sub 14 B

Although calculations of interstitial site dimensions suggest that R sub 2 Fe sub 14 B compounds (R = rare earth) should not be able to absorb N atoms to form R sub 2 Fe sub 14 B-N sub x nitrides, several literature reports of nitrogenation and improved magnetic properties have appeared. We found th...

description Although calculations of interstitial site dimensions suggest that R sub 2 Fe sub 14 B compounds (R = rare earth) should not be able to absorb N atoms to form R sub 2 Fe sub 14 B-N sub x nitrides, several literature reports of nitrogenation and improved magnetic properties have appeared. We found that Nd sub 2 Fe sub 14 B does absorb a considerable amount of nitrogen, up to N/M = 0.26, decomposing the Nd sub 2 Fe sub 14 B to nanocrystalline Fe and unidentified nitride and other species.
