A series of DyFe1-xInxO3(x = 0 to 1 step 0.1)polycrystalline samples have been prepared by solid reaction methods.The crystal structure,refined by the Fullprof,shows that the lattice constants change by the In ions doping,which indicates that the results would be divided into the orthorhombic one in the case of 0≤x≤0.6 and the hexagonal one in the case of 0.7≤x≤1 resulting in a huge distortion of the magnetic sublattice.
