Abstract

Close
- We have investigated the structural and magnetic properties of antiferroelectric A(2)CoTeO(6) perovskites with A = Cd, Ca, Sr, Pb, and Ba. All compounds are antiferromagnetic at low temperatures, with the antiferromagnetic transition temperature slightly decreasing with decreasing ionic size of the A cation. Such a decrease in antiferromagnetic interaction is not observed in A(2)(2+)CoM(6+)O(6) materials with other M6+ cations of similar ionic sizes, suggesting that Te6+ cations affect the electronic and in turn the magnetic structure of the system.
