Investigation of Iron-Based and Topological Superconductors via Point-Contact Spectroscopy
I report results of point-contact spectroscopy (PCS) measurements preformed on a variety of superconductors which are predicted to exhibit unconventional Cooper pairing mechanisms. Point-contact spectra of the iron pnictide ...
Structural Changes and the Nature of Superconductivity in Rare-earth Doped CaFe2As2
Chemical substitution into iron-pnictide parent compounds (e.g. AFe<sub>2<\sub>As<sub>2<\sub> where A=Ba, Sr, or Ca) has proven to be an effective means to induce bulk high-temperature superconductivity in these systems. ...
Frustrated Magnetism and Electronic Properties of Hollandite Oxide Materials
Microporous transition metal oxides with the hollandite structure type have been prepared by standard solid-state techniques with varying compositions. With a nominal formula of AxM8O16 and a framework of edge and ...
Magnetism and superconductivity in topotactically modified transition metal chalcogenides
Inspired by the structure of the simplest iron-based chalcogenide superconductor, FeSe, the class of tetrahedral transition metal chalcogenides (TTMCs) exhibit interesting chemical and physical properties due to its ...
