The Effects of Non-Magnetic and Magnetic Doping on the Skyrmion Hosting Material, Cu2OSeO3
… is the only insulating multiferroic that hosts magnetic skyrmions, which have been hypothesised as an alternative method to store data. These skyrmions arise from competing Heisenberg exchange and Dzyaloshinskii-Moriya interactions due to the non-centrosymmetric arrangement of the material’s …

Magneto-Optical Effects in Manganese-doped Lead Halide Perovskite
Magnetic doping holds a great potential for tailoring material properties of semiconductors via control over exciton-dopant interactions. Hybrid metal-halide perovskites are a new class of high-performance solution-processable semiconductors which combine remarkable optoelectronic performance with …

Scanning tunneling microscopy and spectroscopy of topological materials with broken symmetry
… electronic properties of topological materials. Magnetic doping was then added to induce ferromagnetism, which creates an energy gap in the surface states of (Bi1-xSbx)2Te3. Tunneling conductance spectroscopy was used to examine the correlation between the density of magnetic impurities and the …

Doping Studies of Frustrated Magnets
Doping nonmagnetic materials is known as an effective way of investigating the properties of frustrated magnets. LiCuSbO4 is one of the simplest quasi-one dimensional spin-1/2 magnets which can be modelled with ferromagnetic(FM) nearest neighbour and antiferromagnetic (AFM) next nearest neighbour …

Investigation of magnetic interactions in topological insulators
… This thesis is a comprehensive study of magnetic interactions in topological insulators, from both experimental and theoretical perspective. Generically, there are two approaches to bring TI magnetic, the proximity effect and the conventional transitional metal ion doping. In the …

Growth, Structural and Electrical Characterization of Topological Dirac Materials
… completely insulting from the inside. Moreover, doping topological insulators with magnetic impurities unlocks new avenues for spin memory devices in the form of a single spin polarized dissipationless conduction channel. In topological insulators, there is always a contribution from the inside …

Developing spectroscopic ellipsometry to study II-VI and diluted magnetic semiconductors
… ellipsometer (RAE) to study effects of magnetic and nonmagnetic doping on the £1 and £1 + .11 band gap energies in ZnSe-based II-VI semiconductors. To remove the natural surface oxide overlayer which distorts the intrinsic dielectric response of the sample, a chemical etching technique …
