The polycrystalline sample of Zn doped Fe 1–x Zn x Cr 2 S 4 (x = 0.1, 0.3) were prepared by solid state reaction. The crystal structure was determined to be the normal cubic spinel of space group Fd 3 m and the lattice constants(x = 0.1, 0.3) were a 0 = 9.9967(3) Å and a 0 = 9.9926(3) Å, respectively. The magnetic moment values of Fe 1–x Zn x Cr 2 S 4 for the x = 0.3 were observed higher than that of the x = 0.1. The Néel temperatures were decreased to 153 K (x = 0.1), 135 K (x = 0.3) with Zn substitution concentration. This result is due to the decrease of A‐B superexchange interaction by the replacement of Zn ions for A site. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
