摘要：

The crystal structures and magnetic properties of borate compounds Sr6LnFe(BO3)6 (Ln = La, Pr, Nd, Sm-Lu) were investigated. These compounds crystallize in a hexagonal structure with space group R3¯, in which the Ln and Fe ions form one-dimensional chain structure. From the results of structural analysis, it was found that there is an anti-site disorder between Sr and Ln sites, and its chemical formula can be represented as (Sr6-xLnx)(Ln1-xSrx)Fe(BO3)6. The value of x increases with ionic radius of Ln3+. The results of magnetic susceptibility measurements show that all the Sr6LnFe(BO3)6 are paramagnetic, and the onset of an antiferromagnetic ordering was observed below ∼3 K from the specific heat measurements. © 2016, Elsever B.V.
