Transport signatures and the origin of non-collinear spin textures

Spin and charge transport is vital for spintronics, whereas the origin, detection and understanding of spin textures in magnets is of utmost importance in magnetism. In this thesis, we combine these two research directions to find transport properties of metal/graphene placed on top of a spin textured magnetic insulator. We also study a magnetic system with a very unusual spin texture. In this thesis, we discuss the phenomenological theory behind the spin Hall magnetorsistance in Pt|Cu2OSeO3 heterostructure (Chapter 2), find the resistance anomaly of Graphene|Spiral magnet (Chapter 3), and explain the origin of the unusual 90◦ spin ordering in the multipiezo magnetic insulator Pb2MnO4.
