Investigating the Optical, Magnetic, and Mechanical Properties of La₂NiMnO₆ via Sr-Eu Co-Doping

The study investigates the effect on properties of La2NiMn06 (LNMO) by doping with Co-dopants, Sr-Eu at A-site respectively. The exploration is done by using Density Functional Theory (DFT) in combination with LDA (Local Density Approximation) and Hubbard’s Correction (LDA+U). On comprehensive analysis we show how these dopants influence the properties like optical, magnetic, mechanical, electrical and spintronic characteristics of LNMO. The research reveals the use of dopants modifies the electronic structure of LNMO and the alterations improved the materials dielectric properties which are important for the applications requiring high dielectric constant. Additionally, the doping resulted an improvement in the optical conductivity, improving the features of light absorption and photoconductivity efficiently highly suitable for optoelectronics devices, where light management is essentially in operational process. With related to magnetic properties the doping by Sr-Eu showed an enhancement in properties regarding to spintronics where control of spin is mandatory. The improvement in both the properties (electrical & magnetic) are considerable parameters in energy storage devices in determining its efficiency and effectivity. In addition to it the mechanical properties show resilience and stability while doping by Sr-Eu notable in determining the longevity and durability of devices respectively. On estimation this paper focus on potentiality in technology with wider applications in spintronics, optoelectronics and energy storage devices respectively. The current study and findings provide new ways of synthesizing the materials, providing new alternative paths for the development of exotic materials of tailored functionalities with future prospects in consideration.
