Title: Importance of Specific Heat Characterization when Reporting New Superconductors: An Example of Superconductivity in LiGa₂Rh

Abstract

Here, we show that the full-Heusler compound LiGa₂Rh is a superconductor with T_c = 2.4 K. The new superconductor was found as a result of an intuition-based extension of a database search for superconductors that looked for the presence of peaks in the electronic band structure near the Fermi energy. The measurement of the entropy loss during the transition from the nonsuperconducting to the superconducting state, a straightforward measurement rarely presented in reports of "new" superconducting materials, played a critical role in identifying and isolating the superconducting compound. This study presents a particularly good example of how specific heat measurements are important for the identification and isolation of a new superconductor, since much more frequently reported resistive and magnetic susceptibility characterizations are often not enough to confirm the identification of a new superconducting material.

Journal Article Carnicom, Elizabeth M. ; Kong, Tai ; Klimczuk, Tomasz ; ... - Solid State Communications

Here, we show that the previously unreported ternary σ phases Nb_20.4Rh_5.7Ge_3.9 and Nb_20.4Rh_5.7Si_3.9 are both superconductors with T_c values of approximately 1.9 K. The superconducting transitions were characterized through temperature-dependent magnetic susceptibility, electrical resistance, and specific heat measurements. The Sommerfeld constants, γ, for Nb_20.4Rh_5.7Ge_3.9 and Nb_20.4Rh_5.7Si_3.9 are 89(1) mJ mol-f.u.^–1K^–2 and 86(1) mJ mol-f.u.^–1K^–2 (about 3.0 and 2.9 mJ mol-atom^–1 K^–2), respectively. Here, the normalized specific heat jumps at T_c, ΔC/γT_c, are approximately 1.39 for Nb_20.4Rh_5.7Ge_3.9 and 1.30 for Nb_20.4Rh_5.7Si_3.9, consistent with both materials being weakly coupled BCS type superconductors.

Superconductivity in the superhard boride WB_4.2

Here, we show that the superhard boride WB_4.2 is a superconductor with a T_c of 2.05(5) K. Temperature-dependent magnetic susceptibility, electrical resistivity, and specific heat measurements were used to characterize the superconducting transition. The Sommerfeld constant gamma for WB_4.2 is 2.07(3) mJ mol(^-1) K^-2 and the ΔC/γ T_c = 1.56, which is somewhat higher than what is expected for weakly coupled Bardeen-Cooper-Schrieffer type superconductors. The H _c2 versus T plot is linear over a wide temperature range but does show signs of flattening by the lowest temperatures studied and therefore the zero temperature upper critical field (μ ₀H _c2(0)) formore »« less

Superconductivity in the intermetallic compound Zr₅ Al₄

Journal Article Sobczak, Zuzanna ; Winiarski, M. J. ; Xie, W. ; ... - Europhysics Letters (Online)

Polycrystalline Zr₅Al₄ was synthesized using the arc-melting method. Powder X-ray diffraction confirms the previously reported crystal structure of the Ti₅Ga₄ -type (P6₃/mcm) with lattice parameters: a = 8.4312(6) Å, and c = 5.7752(8) Å. Electrical resistivity and low-temperature magnetic susceptibility measurements indicate that Zr₅Al₄ exhibits superconducting behavior below 2K. The normalized heat capacity jump at T_c = 1.82 K, ΔC/γT_c = 1.50, confirms the bulk superconductivity. The Sommerfeld coefficient γ = 28.5 mJ mol^-1 K^-2 and the Debye temperature Θ_D = 320 K were obtained by fitting the low-temperature heat capacity data.

Superconductivity in the Endohedral Ga Cluster Compound PdGa ₅

Journal Article Ryżyńska, Zuzanna ; Wiśniewski, Piotr ; Kaczorowski, Dariusz ; ... - Journal of Physical Chemistry. C

Superconductivity is observed below T_c = 1.6 K in an endohedral Ga cluster compound PdGa₅ using magnetization and heat capacity measurements. Electronic structure calculations show that the density of states (DOS) at the Fermi level is dominated by Ga s and p states and that the overall shape of DOS is similar to what was found in other endohedral Ga cluster superconductors, such as Mo_xGa_5x+1, ReGa₅, and T₂Ga₉ (T = Rh and Ir). Our results provide a more complete picture of the relationship between the valence electron count and superconductivity in the family of endohedral Ga cluster superconductors.
