Abstract

The effect of substitution of Fe by Cr on the structural and magnetic properties of Fe2TeO6 in the system (Fe1-xCrx)2TeO6, (0<x<1) has been investigated on polycrystalline samples synthesized by solid state reaction. The lattice parameters are found to obey Vegard's law in the entire composition range. The Neel temperature decreases linearly with increasing Cr content from 230 K for x=0 to 90 K for x=1 and is attributed to the weakening of antiferromagnetic exchange interaction as Cr3+ replaces Fe3+ in Fe2TeO6.
