چکیده

ترکیب CuMn2InSe4 با ساختار بلوری چهارضلعی یکی از ترکیبات الماس مانند است که به دلیل وجود یون های مغناطیسی در ساختار آن، دارای خواص مغناطیسی نوری خاصی است. به منظور بررسی خواص ساختاری، نوری و الکترونیکی این ترکیب، محاسبه اصول اول را با روش شبه پتانسیل بر اساس تئوری تابعی چگالی انجام داده ایم. چگالی کل و جزئی حالات برای این ترکیب برای حالت‌های اسپین بالا و پایین مورد مطالعه قرار گرفته است. نتایج نشان‌دهنده مغناطش بالا و هیبریداسیون بالا اوربیتال‌های اتم‌های مس است. نتایج ساختار نواری برای حالت‌های اسپین بالا و پایین، خاصیت نیمه فلزی این ترکیب را ثابت می‌کند. بررسی پراکندگی فونون برای بررسی حالت های نوری و صوتی استفاده شده است. در نهایت، خواص نوری منحصر به فردی برای هدایت الکتریکی، ضریب جذب و بازتاب CuMn2InSe4 مشاهده شد.

چکیده [English]

Abstract: The CuMn2InSe4 compound with a tetragonal crystal structure is one of the diamond-like compounds which has special magneto-optical properties due to the presence of magnetic ions in its structure. In order to study the structural, optical and electronica properties of this compound, we have performed first-principles calculation with the pseudo-potential method based on density functional theory. The total and partial density of states for this compound has been studied for spin-up and spin-down states. The results indicate a high magnetization and high hybridization of the orbitals of Cu atoms. Band structure results for spin-Up and spin-Down states proves the half-metallic property for this compound. Phonon dispersion investigation has been used to investigate the optical and acoustic modes. Finally, unique optical properties was observed for the electrical conductivity, absorption coefficient and reflectivity of CuMn2InSe4.
