We have developed a new method to perform point-contact spectroscopy PCS under pressure, in which a thin-film deposition technique is used for making a point contact. We investigated a pressure dependence of the point-contact spectra of the heavy-fermion superconductor URu 2 Si 2 single crystal. In PCS of URu 2 Si 2 , two characteristic components evolve at low temperatures: one is a symmetric structure with respect to zero bias voltage suggesting a gap of the density of states at the Fermi surface, and the other is an anti-symmetric structure. We observed little change of two components between hidden order and antiferromagnetic phases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
