The binary rare-earth nitrides were covered in Volume 4 of this Handbook series (Hulliger 1979) in a chapter devoted to rare-earth pnictides. The present chapter essentially aims at reviewing ternary and higher order rare-earth nitride materials. 

The physical properties of the rare-earth pnictides have been reviewed by Hulliger (1979). For a long time, rather contradictory results were reported, due mainly in the case of... 

Rare-earth antimonides RSb. Among the rare-earth monopnictides the RSb system has been studied in greatest detail. For a discussion of physical properties of the pnictides see Hulliger (1979). 

It is quite natural that not all authors and not all papers could be included in this review due to the limited amount of space and capability of the author. But since this article is not the only review and probably not the last one on this topic the problems and materials will always be illuminated from different points of view. With respect to magnetic semiconductors we want to recall that non-rare earth compounds like the Cr spinels (Haas, 1970) offer similar effects as the Eu chalcogenides. Also the group of the RE-pnictides may become ferromagnetic semiconductors with increasing purity and perfection of the samples, but at the moment their conduction mechanism is still in discussion (see also F. Hulliger, vol. 4, ch. 33 of this Handbook).
