Abstract In this project, we propose to study the role of the topology in the Condensed MatterPhysics. Particularly, we propose to study two different applications: new topological phases of matter and magnetic topological defects. In our study of topological phases of matter, we want to synthesize three dimensional topological insulators (3D TIs), Dirac semimetals and Weyl semimetals. The aim of this project is to investigate if the Electron Spin Resonance (ESR), which is a microscopic technique, could be useful to complement ARPES measurements. This hypothesis was first pointed by previous works of this group in the half-Heusler family and, latter, by the student master's degree dissertation. Specifically, we want to investigate if the non-trivial topology inside the half-Heusler family reflects in the Crystalline Electrical Field (CEF) effects and in the ESR line shape. In the skyrmions case, we want to synthesize magnetic compounds which have this topological defect in intermetallic nanowires using the metallic-flux nanonucleation (MFNN) technique that was developed in another project by our group and other groups of Unicamp. Besides, our goal is to do transport measurements in a single nanowire, as well ESR measurements in the matrix, to investigate the topological Hall Effect. (AU) | |
