摘要：

We present calculations of interband optical conductivity of the compound Ni3Al using the linear-muffin-tin-orbital method. Calculations are performed using constant matrix elements and calculated matrix elements. We find that matrix elements-play a significant role in influencing the magnitude of optical conductivity sigma(omega) and the position of peaks. Since Ni3Al is weakly ferromagnetic (magnetic moment equal to 0.31 mu(B) per unit cell), we have also calculated sigma(omega) using the ferromagnetic band structure but without spin-orbit coupling. A comparison of our results with experimental data is presented.
