Spin-triplet proximity effects in magnetically controlled heterostructures with s-wave superconductors
… the rapid depairing of conventional spin-singlet Cooper pairs in the presence of a magnetic exchange field. Over the last decade-and-half, experimental evidence has emerged for the generation of spin-triplet Cooper pairs, which have parallel aligned spins, and are therefore compatible with …

Investigation of Iron-Based and Topological Superconductors via Point-Contact Spectroscopy
… which are predicted to exhibit unconventional Cooper pairing mechanisms. Point-contact spectra of the iron pnictide BaFe_{1-x}$Pt$_x$As$_2$ are consistent with a two-gap isotropic s-wave model. This conclusion is supported by previously published results from thermal conductivity, …

SPIN AND CHARGE TRANSPORT IN 2D MATERIALS AND VAN DER WAALS HETEROSTRUCTURES
… existence of spin supercurrent carried by spin-triplet Cooper pairs in NbSe2. Last but not least, the existence of spin supercurrent is further supported by non-local spin valve measurement. A clear spin signal of magnitude up to 4 Ω was observed. Spin lifetime and diffusion length were …

Superconducting phase transitions in hybrid superconducting systems with ferromagnets and spin-orbit coupling
… h_c2. In finite sized samples, singlet-to-triplet conversion results in spin magnetisation at the sample edges. This edge effect suppresses the phase transition. Due to the sample size-dependence, the transition can be controlled in shape-anisotropic samples by rotating the applied magnetic …

Spin-mixing and transport through superconducting interlayers in ferromagnetic Josephson junctions
… memory elements. Supercurrents of spin-aligned triplet Cooper pairs (or ’triplet pairs’) can be generated at magnetically inhomogeneous superconductor/ferromagnet interfaces, and have a longer decay envelope in a ferromagnet than singlet Cooper pairs (or ’singlet pairs’). In this thesis I …

Non-collinear spin textures in oxides for spintronics and superconducting spintronics
… conversion between spin-0 singlet and spin-1 triplet Cooper pairs in an epitaxial oxide ferromagnetic Josephson junction. This starting point has led to four main results: 1. Experiment: anti-ferromagnetic coupling in SrRuO3/La0.7Ca0.3MnO3. These heterostructures are grown on different …
