Infrared Spectroscopy, X-ray Diffraction and Neutron Diffraction Study of BaFe12−xAlxO19 Solid Solutions

Crystal Structure, Magnetic Properties and Thermal Behavior of BaFe11.9In0.1O19 Ferrite

“…As it was previously reported by the results of a study of the crystal structure by X‐ray and neutron powder diffraction methods, the solid solutions of barium hexaferrite substituted by diamagnetic cations such as Al 3+ , In 3+ , Sc 3+ , and Ga 3+ retain the hexagonal symmetry of the unit cell described by the centrosymmetric P6 3 /mmc (No 194) space group. [ 24–28 ] It was also reported that the crystal structure of such substituted barium hexaferrites can be satisfactorily described by the hexagonal non‐centrosymmetric P6 3 mc (No 186) space group. [ 29–31 ] The ionic coordinates have been clarified and the bond lengths and bond angles have been calculated.…”
