Abstract

A new pyrochlore solid solution with formula Bi_1.56Sb_1.48-xNb_xCo_0.96O₇ has been synthesized using ceramic method at 1000°C. Composition dependencies of cell parameters showed a linear increase with niobium x fraction. The IR-active bands characteristic of A and B sites of pyrochlore compound have been detected by infrared spectroscopy. The magnetic susceptibility measurements achieved between 4 and 300 K indicate a paramagnetic behavior with an oxidation state "+2" for the cobalt ion. The results of dielectric measurements show large dielectric loss due to residual electronic conductivity.

<EA>A new pyrochlore solid solution with formula Bi<sub>1.56</sub>
Sb<sub>1.48-x</sub>

 has been synthesized using ceramic method at 1000°C. Composition dependencies of cell parameters showed a linear increase with niobium x fraction. The IR-active bands characteristic of A and B sites of pyrochlore compound have been detected by infrared spectroscopy. The magnetic susceptibility measurements achieved between 4 and 300 K indicate a paramagnetic behavior with an oxidation state "+2" for the cobalt ion. The results of dielectric measurements show large dielectric loss due to residual electronic conductivity.</EA>
