“…The expressions for the first- and second-order quadrupole energies E ( i ) ( I , m ,ϑ,ϕ) can be found in the study of Potočnik et al . ( 34 ). In calculations of powder NMR spectra, initially, a uniform distribution of cos ϑ and φ has been assumed.…”

“…In the penetration depth, λ(T), and the upper critical fi eld, μ 0 H c2 (T), of Y 2 C 3 using a tunnel-diode-based resonant oscillation technique, λ(T) shows T-linear dependence at T<T c indicating the existence of a superconducting gap with line nodes, and the μ 0 H c2 (T) presents a weak upturn at low temperature with a rather high value of about 29 T, which exceeds the weak-coupling Pauli limit [31]. In 139 La and 13 C NMR of La 2 C 3 , 139 La and 13 C NMR shift s in the superconducting state do not diff er from the normal state, and the 139 La spin-lattice relaxation rate is strongly enhanced below T c [32]. Th ese unconventional results can be attributed to the absence of inversion symmetry, which allows the possible mixture of spin-singlet and spin-triplet Cooper pairs in both compounds.…”

The discovery of superconductivity in MgB 2 and B-doped diamond has stimulated the search for new superconducting materials in similar systems containing light elements. In the framework of BCS theory, high frequency phonons induced in a network of light elements can yield a higher superconducting transition temperature (Tc). It shows that light element superconductors provide one of the most promising paths to a room-temperature superconductor taking account of the relationship electronic state and bonding state.

“…However, in these materials it is impossible to disentangle the effects of non-centrosymmetricity from those of strong electron correlations. A possible solution to this issue is an in-depth investigation of weakly correlated NCSCs, such as B 13 – 16 , 17 – 20 , and 21 – 25 .…”

Unconventional superconductivity in non-centrosymmetric superconductors has attracted a considerable amount of attention. While several lanthanide-based materials have been reported previously, the number of actinide-based systems remains small. In this work, we present the discovery of a novel cubic complex non-centrosymmetric superconductor $${\text {Th}}_4{\text {Be}}_{{33}}{\text {Pt}}_{{16}}$$ Th 4 Be 33 Pt 16 ($$I{\bar{4}}3d$$ I 4 ¯ 3 d space group). This intermetallic cage compound displays superconductivity below $$T_{\text {c}} = 0.90 \pm 0.04$$ T c = 0.90 ± 0.04 K, as evidenced by specific heat and resistivity data. $${\text {Th}}_4{\text {Be}}_{{33}}{\text {Pt}}_{{16}}$$ Th 4 Be 33 Pt 16 is a type-II superconductor, which has an upper critical field $${\text {H}}_{{\text {c}}2} = 0.27$$ H c 2 = 0.27 T and a moderate Sommerfeld coefficient $$\gamma _{\text {n}} = 16.3 \pm 0.8$$ γ n = 16.3 ± 0.8 mJ $${\text {mol}}^{-1}_{\text {Th}}$$ mol Th - 1 $${\text {K}}^{-2}$$ K - 2 . A non-zero density of states at the Fermi level is evident from metallic behavior in the normal state, as well as from electronic band structure calculations. The isostructural $${\text {U}}_4{\text {Be}}_{{33}}{\text {Pt}}_{{16}}$$ U 4 Be 33 Pt 16 compound is a paramagnet with a moderately enhanced electronic mass, as indicated by the electronic specific heat coefficient $$\gamma _{\text {n}} = 200$$ γ n = 200 mJ $${\text {mol}}^{-1}_{\text {U}}$$ mol U - 1 $${\text {K}}^{-2}$$ K - 2 and Kadowaki–Woods ratio $$A/\gamma ^2 = 1.1 \times 10^{-5}$$ A / γ 2 = 1.1 × 10 - 5 $$\upmu $$ μ $$\Omega $$ Ω cm $${\text {K}}^2$$ K 2 $${\text {mol}}_{\text {U}}^2$$ mol U 2 (mJ)$$^{-2}$$ - 2 . Both $${\text {Th}}_4{\text {Be}}_{{33}}{\text {Pt}}_{{16}}$$ Th 4 Be 33 Pt 16 and $${\text {U}}_4{\text {Be}}_{{33}}{\text {Pt}}_{{16}}$$ U 4 Be 33 Pt 16 are crystallographically complex, each hosting 212 atoms per unit cell.
