1. Nanoscale spin dynamics in ferromagnetic/normal-metal heterostructures for spin-logic application : Engineering of spin-torque efficiency in Co2FeAl/β-Ta and Ru/FeCo/Ru multi-layers
Abstract : In the present information age, people across the globe generate an enormous digital footprint. Therefore, it is necessary to store and process the information in an elegant way. Spin-logic circuits are being considered potential candidates beyond CMOS integrated computing due to high clock speed, non-volatility, and higher logical efficiency. READ MORE

2. Nanospintronics with Molecular Magnets - Tunneling and Spin-Electric Coupling
Abstract : This dissertation investigates theoretically electric control of the magnetic properties of molecular magnets. Two classes of magnetic molecules are considered. The first class consists of molecules that are spin frustrated. READ MORE

3. Spin-Spin and Spin-Orbit coupling studies of small species and magnetic system
Abstract : The spin of an electron often misleadingly interpreted as the classical rotationof a particle. The quantum spin distinguishes itself from classicalrotation by possessing quantized states and can be detected by its magneticmoment. The properties of spin and its collective behavior with otherfundamental properties are fascinating in basic sciences. READ MORE

4. Magnetization Dynamics in Nano-Contact Spin Torque Oscillators : Solitonic bullets and propagating spin waves
Abstract : Magnetization dynamics in nano-contact spin torque oscillators (STOs) is investigated from an experimental and theoretical point of view. The fundamentals of magnetization dynamics due to spin transfer torque are given. A custom-made high frequency (up to 46 GHz) in large magnetic fields (up to 2. READ MORE

5. Determining and Optimizing the Current and Magnetic Field Dependence of Spin-Torque and Spin Hall Nano-Oscillators : Toward Next-Generation Nanoelectronic Devices and Systems
Abstract : Spin-torque and spin Hall nano-oscillators are nanoscale devices (about 100 nm) capable of producing tunable broadband high-frequency microwave signals ranging from 0.1 GHz to over 65 GHz that several research groups trying to reach up to 200 - 300 GHz. READ MORE
