Yg. Wang et al., STRUCTURE AND MAGNETIC-PROPERTIES OF ND2FE17-XMNX COMPOUNDS (X=0 TO 8), Physica status solidi. a, Applied research, 157(1), 1996, pp. 153-158
The effect of Mn on structure and magnetic properties of Nd2Fe17-xMnx
compounds has been studied. Substitution of Mn for Fe does not change
the structure of Nd2Fe17 and all the investigated Nd2Fe17-xMnx compoun
ds (x = 0 to 8) crystallize in Th2Zn17 structure. Upon substitution of
Mn, the lattice constants decrease after a small initial increase. an
d then increase again. Substitution of Mn for Fe causes a monotonous d
ecrease of the Curie temperature. The saturation magnetization of Nd2F
e17-xMnx compounds decreases dramatically with increasing Mn content.
The moments of the Mn atoms in these compounds are also discussed.
