This paper discusses the difference in permittivity at infrared frequencies between Ba(Mg 1/3 Ta 2/3 )O 3 (BMT) and Ba(Mg 1/3 Nb 2/3 )O 3 (BMN) based on a first-principles calculation. The permittivity, far-infrared and Raman spectra are successfully computed. Analysis of these results shows that th
