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

摘要

The influences of Al doping on the structural, magnetic and dynamical properties of BaFe12-xAlxO19 solid solutions (x = 0.1-1.2) have been studied by using a combination of X-ray diffraction, neutron diffraction and infrared spectroscopy. The magnetic moment of every Fe atom, including combinations, has been defined, and the magnetic moment of Fe3+ ions was found to decrease as the concentration of Al3+ diamagnetic ions in the combinations increased. Studies carried out by using infrared spectroscopy showed that four oscillations under normal conditions in these combinations. The results obtained by using infrared spectroscopy for BaFe12-xAlxO19 combinations were compared with the results obtained by using Raman spectroscopy.
