We report a globally reversible effect of electronic tuning on the magnetic phase diagram in CeCoIn(5) driven by electron (Pt and Sn) and hole (Cd, Hg) doping. Consequently, we are able to extract the superconducting pair breaking component for hole and electron dopants with pressure and codoping studies, respectively. We find that these nominally nonmagnetic dopants have a remarkably weak pair breaking effect for a d-wave superconductor. The pair breaking is weaker for hole dopants, which… 
Reemergent superconductivity and avoided quantum criticality in Cd-doped CeIrIn(5) under pressure.
We investigated the electrical resistivity and heat capacity of 1% Cd-doped CeIrIn_{5} under hydrostatic pressure up to 2.7 GPa, near where long-range antiferromagnetic order is suppressed and bulk
Evidence for Coexistence of Bulk Superconductivity and Itinerant Antiferromagnetism in the Heavy Fermion System CeCo(In1−xCdx)5
The suppression of the antiferromagnetic order appears to be driven by a modification of the bandwidth/carrier concentration, implying that the electronic structure and consequently the interplay of superconductivity and magnetism is strongly affected by hydrostatic and chemical pressure.
Superconductivity and Non-Fermi-Liquid Behavior in the Heavy-Fermion Compound CeCo1−xNixIn5
The effect of off-plane impurity on superconductivity and non-Fermi-liquid (NFL) behavior in the layered heavy-fermion compound CeCo1−xNixIn5 is investigated by specific heat, magnetization, and

’ s Choice Topological analysis of CeMIn 5 ( M = Co , Rh ) electron charge densities
Recently, CeRhIn5 and CeCoIn5 with very different behaviors at ambient pressure were experimentally measured to exhibit comparable properties after applying pressure or doping impurity. Here, we
Pressure and temperature dependence of the Ce valence and c -f hybridization gap in Ce T In 5 (T =Co ,Rh ,Ir ) heavy-fermion superconductors
Pressure- and temperature-induced changes in the Ce valence and c-f hybridization of the Ce115 superconductors have been studied systematically. Resonant x-ray-emission spectroscopy indicated that
Thermal and transport properties of U2Pt(x)Ir(1-x)C2.
The role of electronic tuning in this system is demonstrated and thermal and transport properties of U2Pt x Ir1-x C2 shows an upturn at low temperature, consistent with the expectations of enhanced quantum fluctuations in the presence of an underlying quantum critical point.
Pressure dependence of the electronic structure of 4f and 3d electron systems studied by X-ray emission spectroscopy
ABSTRACT Techniques based on X-ray emission spectroscopy (XES) have been utilized to investigate pressure-induced changes in the electronic structure in samples subject to high pressure in the
