Abstract
We have succeeded in synthesizing almost single phase samples of the layered oxypnictides LnOZnPn (Ln = rare earths, Pn = P, As, Sb) with ZrCuSiAs type structure (P4/nmm), and investigated the magnetic properties of them. They are isostructural to the layered oxychalcogenides LaOCuCh (Ch = chalcogen elements). The lattice parameters decrease linearly with decreasing ionic radius of Ln. The value of the magnetic susceptibility of LaOZnSb is about −3.3 × 10−4 emu/mol Oe and almost temperature independent above 100 K. The effective magnetic moments μeff of CeOZnSb and PrOZnSb, estimated from the temperature dependence of the inverse magnetic susceptibility above 100 K, are 2.37 and 3.28 μB, respectively. These correspond to the trivalent free ion values.Keywords
