Abstract:
The electronic structure of the Mn2CrAl Heusler alloy is calculated and its optical properties are studied in this work. The anomalous behavior of the optical properties of the alloy in the IR region of spectrum, namely, the absence of the contribution of intraband absorption and the low level of interband absorption, were found. Such peculiarities of the optical spectrum indicate the existence of low-energy gaps in the band spectrum of the alloy, which was found by calculations of electronic structure of the alloy.
