We report the discovery of pressure-induced superconductivity in a semimetallic magnetic material CeTe$_{1.82}$. The superconducting transition temperature $T_{SC}$ = 2.7 K (well below the magnetic ordering temperatures) under pressure ($>$ 2 kbar) is remarkably high, considering the relatively low carrier density due to a charge-density-wave transition associated with lattice modulation. The coexisting magnetic structure of a mixed ferromagnetism and antiferromagnetism can provide a clue for this high $T_{SC}$. We discuss a theoretical model for its possible pairing symmetry and pairing mechanism.

We report the normal-state transport and magnetic properties of a pressure-induced superconductor CeTe$_{1.82}$. We found that the applied pressure is required to increase the Kondo temperature scale ($T^*_{rm K} sim$ 170 K), associated with the two- dimensional motion of the carriers confined within the Te plane. Both the short-range ferromagnetic ordering temperature ($T_{rm SRF} sim$ 6 K) and the long-range antiferromagnetic transition temperature ($T_{rm N} sim$ 4.3 K) are slightly increased with pressure. We suggest that the application of pressure enhances a coupling between the 4$f$ and conduction electrons. We also found that the field effect on the transport under pressure is analogous to that at ambient pressure, where a large magnetoresistance is observed in the vicinity of $T_{rm SRF}$.
We investigate properties below T_c of odd-frequency pairing which is realized by antiferromagnetic critical spin fluctuations or spin wave modes. It is shown that Delta(epsilon_n) becomes maximum at finite epsilon_n, and Delta(pi T) becomes maximum at finite T. Implications of the present results to the experimental results of CeCu_2Si_2 and CeRhIn_5 are given.

It is expected that at weak to intermediate coupling, d-wave superconductivity can be induced by antiferromagnetic fluctuations. However, one needs to clarify the role of Fermi surface topology, density of states, pseudogap, and wave vector of the ma gnetic fluctuations on the nature and strength of the induced d-wave state. To this end, we study the generalized phase diagram of the two-dimensional half-filled Hubbard model as a function of interaction strength $U/t$, frustration induced by second-order hopping $t^{prime}/t$, and temperature $T/t$. In experiment, $U/t$ and $t^{prime}/t$ can be controlled by pressure. We use the two-particle self-consistent approach (TPSC), valid from weak to intermediate coupling. We first calculate as a function of $t^{prime}/t$ and $U/t$ the temperature and wave vector at which the spin response function begins to grow exponentially.D-wave superconductivity in a half-filled band can be induced by such magnetic fluctuations at weak to intermediate coupling, but only if they are near commensurate wave vectors and not too close to perfect nesting conditions where the pseudogap becomes detrimental to superconductivity. For given $U/t$ there is thus an optimal value of frustration $t^{prime}/t$ where the superconducting $T_c$ is maximum. The non-interacting density of states plays little role. The symmetry d$_{x^{2}-y^{2}}$ vs d$_{xy}$ of the superconducting order parameter depends on the wave vector of the underlying magnetic fluctuations in a way that can be understood qualitatively from simple arguments.
Measurements of specific heat and electrical resistivity in magnetic fields up to 9 T along [001] and temperatures down to 50 mK of Sn-substituted CeCoIn5 are reported. The maximal -ln(T) divergence of the specific heat at the upper critical field H_ {c2} down to the lowest temperature characteristic of non-Fermi liquid systems at the quantum critical point (QCP), the universal scaling of the Sommerfeld coefficient, and agreement of the data with spin-fluctuation theory, provide strong evidence for quantum criticality at H_{c2} for all x < 0.12 in CeCoIn5-xSnx. These results indicate the accidental coincidence of the QCP located near H_{c2} in pure CeCoIn5, in actuality, constitute a novel quantum critical point associated with unconventional superconductivity.
SmS, a prototypical intermediate valence compound as well as a candidate material for correlated topological insulator, has been studied by performing high-pressure nuclear magnetic resonance measurements on a $^{33}$S-enriched sample. The observatio n of an additional signal below 15-20~K above a nonmagnetic-magnetic transition pressure $P_{rm c2} = 2.0$~GPa gives evidence for the magnetic transition. The absence of a Curie-term in the Knight shift near $P_{rm c2}$ indicates that the transition occurs in electronic states where the localized character of $4f$ electrons is screened through a substantial hybridization. Two distinguishable signals coexist during the stepwise evolution of magnetic volume fraction with lowering temperature near $P_{rm c2}$, which is well described in the regime of first-order transition. The fact that hyperfine fields from the ordered moments cancel out at the S site leads us to a conclusion that the ordered phase has the type II antiferromagnetic structure.
