Magnetic dilution of complex ferrates

• The magnetic and structural properties of La1+0.85yBa1-0.85yFeyAl1-yO4 (0.0056less than or equal toyless than or equal to0.088) solid solutions have been investigated to demonstrate the dependence of the valence state of iron atoms on the composition of sublattice. From the magnetic susceptibility measurements. the coexistence of Fe(II)-Fe(III) hetero valence states has been confirmed and the results showed the tendency of these atoms to form clusters.
