Hence, the net magnetic moment is given by the sum of the magnetic moments of A and B sublattices, i.e., M = M B À M A . In the above cationic distribution, Zn 2 +, Li 1 +, Ti 4 + and V 5 + are non-magnetic and do not contribute to the sublattice magnetization. However, V 5 + substitution leads to a replacement of Fe 3 + ions at the A-site.
