Magnetic properties of epitaxial topological insulator Bi₂Te₃/MnTe bilayer and pulsed laser deposited polycrystalline CoFeB thin films

Most electronic devices are made of tiny transistors and capacitors. But there is a limitation on how small these devices can be made up to. This limitation leads to consequences such as super magnetism and overheating of the device. This problem can be avoided by exploring the spin rather than the charge property of an electron giving rise to a new field called spintronics. The thesis gives an outline about the characterization of magnetic thin films like Cobalt-Iron-Boron and magnetic topological insulator films that can be potentially used in magnetic spintronics memory-based devices. The first section includes the theory behind spintronics and topological insulators. The second section describes the experimental techniques used behind achieving the results. And last but not least are the results and their analysis.
