The full width at half maximum (FWHM) of the X-ray diffraction peak (002), and the normalized magnetic moment difference of field-cooled (FC) and zero-field-cooled (ZFC) processes as a function of \(\hbox{A}_{1\textrm{g}}/\hbox{E}^{1}_{2\textrm{g}}\). Both follow the same tendency and are positive in the \(\hbox{A}_{1\textrm{g}}/\hbox{E}^{1}_{2\textrm{g}}\). Larger lattice dislocation leads to larger FWHM. These results imply the element replacement distorts the lattice and enhances intrinsic ferromagnetism
