Abstract: Nanostructured magnetic material offers great advancement in nano-scale devices. My research consists of the investigation of spin dynamics and microwave device fabrication using magnetic nanostructures. I have fabricated epitaxial ferromagnetic thin film of Full Heusler Alloy (Co2FeSi), and bilayers with 2D Transition Metal Dichalcogenide Molybdenum disulfide (TMD MoS2, etc.). Full Heusler alloy Co2FeSi is a spectacular material system that has a very low Gilbert damping, high curie temperature, and half-metallic nature. Thin films of Co2FeSi were fabricated on a (001) oriented MgO substrate using a Pulsed Laser Deposition as well as by using a magnetron sputtering system. (i) A detailed investigation of magnetization dynamics and magnetocrystalline anisotropies has been conducted using the Ferromagnetic Resonance (FMR) technique to describe a favorable thickness regime of the epitaxial Co2FeSi film that can be made useful in spintronic applications.
