Retracted to Spin Seebeck Effect in Fe/Co and Co/Pt layers of Thin Films Using First Principle and Experimental Setup

Abstract

This paper was retracted and resubmitted for the review process.
This research is focusing to examining the electronic structure and electrical properties of the Fe/Co and Co/Pt systems
in comparison with the Fe/Pt system through the use of Density Functional Theory (DFT). The results indicate that the Fe/Co and Co/ Pt systems exhibit significantly less electrical mismatch than the Fe/ Pt system, as evidenced by a broader distribution of the Total Density of States (TDOS) near the Fermi energy level. Further analysis of the Projected Density of States (PDOS) for the d orbitals of Fe and Co in the Fe/Co system, and of Co and Pt in the Co/ Pt system, confirms that the predominant characteristics of both systems are driven by the influence of d orbitals. This insight is critical for the selection of materials for the investigation of the Spin Seebeck Effect (SSE) , particularly in understanding the electrical conductivity and magnetic properties of the materials of interest prior to experimental trials. This study deepens the understanding of the relationship between electronic structure and the electrical and magnetic properties of materials, which is vital for the design and application of materials in spintronics technology, especially in studying the Spin Seebeck Effect. This phenomenon involves the conversion of thermal energy into electrical energy using the spin of electrons.
