Interplay of structural distortion and the magnetic properties with the evolution of localized band structure explain the gradual transition from a three-dimensional antiferromagnet to a low-dimensional frustrated magnetic system along the series. Detailed study of exchange mechanism in this system explores various possibilities of complex magnetic interaction. Electronic structure of this series,","authors_text":"Debjani Karmakar, J. V.
