Notes:
Structural, magnetic, dielectric properties and Mossbauer effect wereinvestigated on complex perovskite with composition AFe〈sub〉2/3〈/sub〉B〈sub〉1/3〈/sub〉O〈sub〉3〈/sub〉 (A=Ca,Sr,Pb,Ba;B=W,Te). The most striking feature of this type of complex perovskites is the coexistence of magnetic and antiferroelectric types of ordering in a certain temperature interval. It was found that ferrimagnetic Ca and Sr compounds belong to a partially ordered perovskite structure, and antiferromagnetic Pb phase to a disordered one. The possible models for nuclear and magnetic structures were proposed in accordance with the observed dielectric and magnetic properties
