Electrical and Magnetic Properties of LnOZnPn (Ln: Rare Earths; Pn: P, As, Sb).-LnOZnPn (Ln: La, Ce, Pr, Nd; Pn: P, As, Sb) single phases are synthesized by solid state reactions of stoichiometric mixtures of Ln, Zn, La2O3, ZnO, Nd2O3, and Pn (1173 K, 48 h). The samples are characterized by powder XRD, electrical resistivity, and magnetization measurements. LnOZnP with Ln: La, Ce crystallize in the tetragonal space group P4/nmm, while the other LnOZnP compounds crystallize in the trigonal space group R3m. All the LnOZnAs and LnOZnSb compounds crystallize in the space group P4/nmm. The electrical resistivity has a maximum at Ln: Ce and decreases with the atomic number of Ln in LnOZnAs and LnOZnAb. While LnOZnPn (Ln: La, Ce, Pr; Pn: P, As) are semiconducting, LnOZnSb (Ln: La, Ce) exhibit a metal-semiconductor transition, and NdOZnPn (Pn: As, Sb) become metallic. While LaOZnPn phases show diamagnetism, other LnOZnPn compounds are paramagnetic. -(TAKANO*, Y.; KOMATSUZAKI, S.; KOMASAKI, H.; WATANABE, T.; TAKAHASHI, Y.; TAKASE, K.; J.
