Current-induced torques in ferromagnets at room temperature
… the sample while sweeping the external magnetic field, and measure the longitudinal DC voltage. From a symmetry analysis of the ferromagnetic resonance lineshape, the amplitudes and directions of the CITs parameterised by an effective magnetic field are accurately estimated. In Chapter 4, YIG …

Towards building a prototype spin-logic device
… This has replaced the more traditional Oersted-field control used in field-MRAMs and allowed further scaling of magnetic-memories. A less obvious con- sequence of STT is that it has made possible a logic-technology based on magnets controlled by spin-polarized currents. Charge-coupled …

High Anisotropy Magnetic Materials for Data Storage and Spintronic Memory
… anisotropy magnetic materials requires large Oersted field or spin current. One way to decrease the switching energy is to lower the anisotropy during the switching process with an applied strain or heat. This scheme retains thermal stability during storage and makes write energies feasible …

Geometrical control of domain walls and the study of domain wall properties of materials with perpendicular magnetic anisotropy
… attention due to their ability to be moved by field and/or current and corresponding potential applications in high speed memory or logic devices. I will then discuss how to geometrically control the behaviors of DWs in a ferromagnetic nanowire. I will first discuss how natural geometry …

Electrical control of spin dynamics in spin-orbit coupled ferromagnets
… the spin-Hall effect and a Rashba spin-orbit field have both been reported in these materials. These spin-orbit torques may allow commercialisation of magnetic random access memories with higher efficiency than previous technologies. However, the exact origin of the torques is still not well …

Magnetodynamics of pseudo spin valves investigated using co-planar waveguide and spin torque ferromagnetic resonance techniques
… The micromagnetic simulations suggest that the rfOersted field in the vicinity of the NC plays the dominant role in generating the spectra observed.ii)The exchange-dominated spin wave is tuned using lateral current spread. To this end, different thicknesses of the Cu bottom layer are used to …
