“…Therefore, the enhancement of T c in layered CeMIn 5 over CeIn 3 has been suggested to be due to their quasi-2D structure [4,14,22]. Our results suggest that the small window for the spin fluctuations regime in CeIn 3 may also be partly responsible for its lower T c .…”

We report the novel pressure(P ) -temperature(T ) phase diagram of antiferromagnetism and superconductivity in CeRhIn5 and CeIn3 revealed by the 115 In nuclear-spin-lattice-relaxation (T1) measurement. In the itinerant magnet CeRhIn5, we found that the Néel temperature TN is reduced at P ≥ 1.23 GPa with an emergent pseudogap behavior. In CeIn3, the localized magnetic character is robust against the application of pressure up to P ∼ 1.9 GPa, beyond which the system evolves into an itinerant regime in which the resistive superconducting phase emerges. We discuss the relationship between the phase diagram and the magnetic fluctuations.PACS numbers: PACS: 74.25. Ha, 74.62.Fj, 74.70.Tx, 75.30.Kz, 76.60.Gv It has been reported that a superconducting (SC) order in cerium (Ce)-based heavy-fermion (HF) compounds takes place nearby the border at which an antiferromagnetic (AF) order is suppressed by applying pressure (P ) to the HF-AF compounds CeCu 2 Ge 2 ,[1] CePd 2 Si 2 [2] and CeIn 3 [3]. The superconductivity in these compounds, however, occurs only in extreme conditions where the pressure exceeds ∼ 2 GPa and temperature (T ) is cooled down below ∼ 1 K. Indeed the experiments were restricted mainly to transport measurements. The discovery of P -induced HF superconductors in Ce-based HF-AF compounds has stimulated further experimental works under P [4,5,6,7]. In order to gain profound insight into a relationship between magnetism and superconductivity in HF systems, systematic NMR/NQR experiments under P are important, since they can probe the evolution of the magnetic properties toward the onset of SC phase.Recently, Hegger et al. found that a new HF material CeRhIn 5 consisting of alternating layers of CeIn 3 and RhIn 2 reveals an AF-to-SC transition at a relatively lower critical pressure P c = 1.63 GPa than in all previous examples [1,2,3]. The SC transition temperature T c = 2.2 K is the highest one to date among P -induced superconductors [4]. This finding has opened a way to investigate the P -induced evolution of both magnetic and SC properties over a wide P range. In the previous paper [7], the 115 In NQR study of CeRhIn 5 has clarified the P -induced anomalous magnetism and unconventional superconductivity. In the AF region, the Néel temperature T N exhibits a moderate variation, while the internal field H int at 115 In(1) site in the CeIn 3 plane due to the magnetic ordering is linearly reduced in P = 0 -1.23 GPa, extrapolated to zero at P * = 1.6 ± 0.1 GPa. This P * is comparable to P c = 1.63 GPa at which the SC signature appears [4], which was indicative of a second-order like AF-to-SC transition rather than the first-order one suggested previously [4]. At P = 2.1 GPa, it was found that the nuclear spin-lattice relaxation rate 1/T 1 reveals a T 3 dependence below the SC transition temperature T c , which shows the existence of line-nodes in the gap function [7]. It is, however, not yet clear how the electronic states change with P when the AF phase evolves into the SC phase.On the other hand, CeIn 3 c...

“…Band structure calculations and de Haas-van Alphen (dHvA) measurements indicate that the 115 materials have a complicated quasi-2D Fermi surface (FS) composed of multiple electron and hole orbits. 22,23,24,25,26 When considering the novel properties of the 115 compounds it is critical to differentiate between phenomena that are controlled by prosaic single-electron physics and those determined by correlated electron interactions.…”

The in-plane Hall coefficient R H (T ) of CeRhIn 5 , CeIrIn 5 , and CeCoIn 5 and their respective nonmagnetic lanthanum analogs are reported in fields to 90 kOe and at temperatures from 2 K to 325 K. R H (T ) is negative, field-independent, and dominated by skew-scattering above ∼ 50 K in the Ce compounds. R H (H → 0) becomes increasingly negative below 50 K and varies with temperature in a manner that is inconsistent with skew scattering. Field-dependent measurements show that the low-T anomaly is strongly suppressed when the applied field is increased to 90 kOe. Measurements on LaRhIn 5 , LaIrIn 5 , and LaCoIn 5 indicate that the same anomalous temperature dependence is present in the Hall coefficient of these non-magnetic analogs, albeit with a reduced amplitude and no field dependence. Hall angle (θ H ) measurements find that the ratio ρ xx /ρ xy = cot(θ H ) varies as T 2 below 20 K for all three Ce-115 compounds. The Hall angle of the La-115 compounds follow this T-dependence as well. These data suggest that the electronic-structure contribution dominates the Hall effect in the 115 compounds, with f -electron and Kondo interactions acting to magnify the influence of the underlying complex band structure. This is in stark contrast to the situation in most 4f and 5f heavy-fermion compounds where the normal carrier contribution to the Hall effect provides only a small, T-independent background to R H .

“…Because of the high quality of single crystals that result from flux growth-based crystal growth, substantial progress has been made in quantum oscillation studies of CeMIn 5 [22][23][24][25][26]. From a broad perspective, reasonable agreement is found between LDA band structure calculations and de Haas-van Alphen oscillation measurements.…”

“…Another normal-state feature of CeMIn 5 revealed by high-field measurements is the ubiquitous presence of metamagnetic transitions. CeRhIn 5 [22,39], CeIrIn 5 [37] and CeCoIn 5 [33] all display field-induced transitions in heat capacity or magnetization.…”

We review the properties of the recently discovered CeMIn5 (M=Co, Ir, Rh) heavy fermion superconductors and discuss the present state of our understanding of these materials. A particular focus is the role that magnetic fields have played in elucidating the properties of these materials. Specifically, we discuss quantum oscillation measurements on CeMIn5, the influence of applied field on the linear coefficient of specific heat, g, and the nature of the H-T phase diagrams in both the normal and superconducting states of these materials.
