Double perovskites are interesting in the field of material sciences because of their multifunctional properties. Different researches have been done and several investigations have been carried out to explore these compounds. Here in this paper, we have explored one of the less investigated compounds i.e., Nd₂NiMnO₆. Although few experimental studies have been made and some results have been pointed out, still we are going to explore some properties of Nd₂NiMnO₆ using Density Functional Approach. Band structure and density of state (DOS) studies of the material in spin up and spin down channels disclose the semiconducting behavior of Nd₂NiMnO₆. The variation of dielectric constant with frequency and the variation of susceptibility with wavelength have also been presented with the explainable trends. The results also reveal the anisotropic nature in dielectric function and susceptibility of the compound.

由于其多功能特性，双钙钛矿在材料科学领域很有趣。已经进行了不同的研究并进行了多项调查来探索这些化合物。在本文中，我们探索了一种研究较少的化合物，即 Nd ₂ NiMnO ₆。尽管很少进行实验研究并指出了一些结果，但我们仍将使用密度泛函方法探索 Nd ₂ NiMnO _{6 的}一些性质。自旋向上和自旋向下通道中材料的能带结构和态密度 (DOS) 研究揭示了 Nd ₂ NiMnO ₆的半导体行为. 介电常数随频率的变化和磁化率随波长的变化也呈现出可解释的趋势。结果还揭示了该化合物的介电函数和磁化率的各向异性性质。
