Multiple phase transitions in Ce(Rh,Ir,Co)In5

Evolution of magnetism in Pd-substituted Ce2RhIn8 single crystals

“…Similar behavior is observed for compounds substituted with Co and Ir compared to their more 2D counterparts (n = 1) [9,27].…”

“…X-ray powder diffraction measurements confirmed the HoCoGa 5 structure with lattice parameters in agreement with previous results. 14 The dc magnetic susceptibility ͑T͒ = M / H measurements were performed by means of a commercial superconducting quantum interference device ͑SQUID͒ magnetometer ͑Quan-tum Design͒ in fields of 1 kOe in the temperature range 2 -350 K. Heat capacity C p ͑T͒ measurements were carried out using the thermal relaxation technique with a commercial calorimeter in the temperature range 0.5-300 K. The electrical resistivity ͑T͒ was measured in a commercial 4 He cryostat, using a four-probe ac technique in the temperature range of 1.8-300 K under zero applied field. Bar-shaped samples were cut along the principal axes, and a current was applied along the ͓100͔ direction.…”

“…Further, pressure-dependent and doping-dependent studies have revealed extremely rich phase diagrams that include the microscopic coexistence of superconductivity and magnetism. [4][5][6][7] Quite recently, superconductivity has also been reported in isostructural PuCoGa 5 and PuRhGa 5 . 8,9 Although less is known about these plutonium-based materials, the underlying physics appears to be similar 10 to that of CeMIn 5 and, in particular, seems to rely on the existence of at least partially localized f electrons.…”

Single crystal study of the layered heavy fermion compounds Ce2PdIn8, Ce3PdIn11, Ce2PtIn8 and Ce3PtIn11

“…In conjunction with the already known Ce n T m In 3n+2m compounds, they significantly enrich the spectrum of dimensionality evolution from 2D-like to 3D systems. Besides varying pressure [8] and substitution doping [9], structural dimensionality represents another parameter suitable for tuning the quantum critical point in the Ce n T m In 3n+2m compounds, spanning from more 2D-like CeTIn 5 (or even CePt 2 In 7 ) to more 3D-like Ce 3 PdIn 11 and Ce 3 PtIn 11 structures [2,7,10,11].…”
