Confinement effects in triplet superconducting systems

In this thesis we present our research on two triplet superconductors in two distinct systems. The first part of this report is concerned with SRO, a leading candidate for p-wave chiral pairing, where the aim is to develop an efficient method to fabricate mesoscopic structures suitable for investigating confinement effects. A number of top-down techniques are implemented to obtain micron-sized crystals that can be readily structured and contacted for transport measurements. We show that tape exfoliation, similar to the scotch tape method, can be used to achieve the desired results. The second part of this report deals with triplet superconductivity in Superconductor-ferromagnet hybrids. In particular, we investigate the behavior of a Josephson junction located in a ferromagnetic disk. Applying the model developed by Dynes & Fulton [1] critical current density across the junction is estimated. We show that the triplet supercurrent is split into two distinct channels defined by the...Show moreIn this thesis we present our research on two triplet superconductors in two distinct systems.
