High-pressure study of the ground- and superconducting-state properties of CeAuSi
Gernot W. Scheerer, Gaétan Giriat, Zhi Ren +2
The pressure-temperature-phase diagram of the new heavy-fermion superconductor CeAuSi is markedly different from those studied previously. Indeed, superconductivity emerges…
Collapse of the Mott gap and emergence of a nodal liquid in lightly doped SrIrO
A. de la Torre, S. McKeown Walker, F. Y. Bruno +13
Superconductivity in underdoped cuprates emerges from an unusual electronic state characterised by nodal quasiparticles and an antinodal pseudogap. The relation between this state…
High pressure investigation of superconducting signatures in CeCuSi : ac- magnetic susceptibility and heat capacity, resistivity and thermopower
Gaétan Giriat, Zhi Ren, Pablo Pedrazzini +1
Taking advantage of a novel multiprobe setup we have measured, on a unique sample, the ac-magnetic susceptibility, the resistivity, the ac-specific heat and the thermopower of the…
Effect of disorder on the pressure-induced superconducting state of CeAu2Si2
Z. Ren, G. Giriat, G. W. Scheerer +2
CeAu2Si2 is a newly discovered pressure-induced heavy fermion superconductor which shows very unusual interplay between superconductivity and magnetism under pressure. Here we comp…
Giant overlap between the magnetic and superconducting phases of CeAu2Si2 under pressure
Z. Ren, L. V. Pourovskii, G. Giriat +3
High pressure provides a powerful means for exploring unconventional superconductivity which appears mostly on the border of magnetism. Here we report the discovery of pressure-ind…
