The proposed research will involve the growth of FeGe multilayer films using sputtering techniques, and characterization through advanced techniques such as X-ray diffraction, transmission electron microscopy, and magnetometry. The transport properties of the films will be further examined using Hall effect measurements. The ultimate goal of this study is to contribute to the fundamental understanding of magnetic thin films and to potentially pave the way for innovative applications in magnetic and spintronic devices.IntroductionThin films of transition metal compounds, such as FeGe, have attracted considerable attention due to their magnetic and electronic properties that can be tailored by controlling their structure and thickness. FeGe belongs to the family of transition metal silicides and germanides, which exhibit diverse physical properties, including giant magnetoresistance (GMR), tunnel magnetoresistance (TMR), and spin dependent transport. FeGe has a high magnetostriction constant, allowing for efficient coupling between magnetic and mechanical degrees of freedom, which is essential for the development of magnetoelastic devices. Additionally, FeGe has a Curie temperature (TC) of approximately 200 K, which is relatively high compared to other transition metal compounds. In this proposed study, we aim to grow FeGe nanoscale multilayer films and investigate their structural and magnetic properties. The films will be grown using RF magnetron sputtering, which is a well-established technique for depositing thin...
