Abstract

New pyrochlore compounds Sm1.6M0.4Ti1.6Nb0.4O7 (M = Cu, Ni) are synthesized by a wet chemical method. The crystal structure of the compounds belongs to a cubic system with a cubic face-centered cell. The temperature dependence of the inverse susceptibility of Sm1.6M0.4Ti1.6Nb0.4O7 (M = Cu, Ni) in the paramagnetic region shows the ferrimagnetic behavior of the compounds. Fitting to the experimental plot of the inverse susceptibility of the compound versus temperature was performed. The temperature at 1/χ = 0(TFN) is (150 ± 5)K for Sm1.6Cu0.4Ti1.6Nb0.4O7 and (164 ± 5) K for Sm1.6Ni0.4Ti1.6Nb0.4O7. The compounds are weak ferrimagnets, not spin glasses.
