“…Figure 10 The blue solid line in Figure 10 shows the trend in the YAu 2-x Pd x In system, in which Au atoms can be fully replaced by Pd atoms, resulting in a continuous change of the valence electrons from 26 to 28 18 . Seven different compositions were studied and their T c s are shown as the stars on the Figure. Fifty years ago, Matthias proposed that the superconducting critical temperature of pure elements has a maximum for the ratio of valence electrons / atom slightly below 5 21 .…”

Several physical properties of the superconducting Heusler compounds, focusing on two systems (Y, Lu, Sc)Pd 2 Sn and APd 2 M, where A=Hf, Zr and M=Al, In, are summarized and compared. The analysis of the data shows the importance of the electron-phonon coupling for superconductivity in this family. We report the superconducting parameters of YPd 2 Sn, which has the highest T c among all known Heusler superconductors.

“…The testing of elastic and inelastic neutron scattering for Pd 2 SnEr was carried out, which proved that Pd 2 SnEr turned into superconductor at T c = 1.17 K. Only when temperature conditions met T > T c , the antiferromagnetic correlations would occur. The maximum critical temperature was found in Pd 2 YSn, which was revealed as the Heusler alloy [27].…”

This work is devoted to investigate the elasticity, anisotropy, plastic properties, and thermal conductivity of PdSnYb, PdSn 2 Yb and Heusler alloy Pd 2 SnYb via employing the first-principles. The magnetic properties of Pd 2 SnYb, PdSnYb and PdSn 2 Yb are obtained by the geometry optimization combining with spin polarization. And the stability of these three kinds of materials is ensured by comparing with the enthalpy of formation and binding energy. The Fermi energy has same trend with stability. The details of bulk and Young's modulus are demonstrated in 3D plots, embodied the elastic anisotropies of PdSnYb, PdSn 2 Yb, and Pd 2 SnYb. The calculations of plastic properties are also anisotropic. And the minimum thermal conductivities are small enough for these three materials to be used as thermal barrier coatings.

“…6,7 and superconductivity. [8][9][10] Considering the fact that elemental Ni is ferromagnetic, Ni-rich intermetallic alloys are expected to order magnetically instead of demonstrating superconductivity. Therefore, from fundamental science point of view, the observation of superconductivity in Ni based Heusler alloys are of great interest.…”

The superconducting properties of a series of Zr1+xNi2-xGa and Zr1-xNi2+xGa compounds have been investigated by x-ray diffraction, electrical resistivity, dc magnetization, and ac susceptibility measurements. While the parent compound, ZrNi2Ga, exhibited the cubic L21 Heusler structure, multiple non-cubic structures formed in the Zr and Ni rich doped materials. For x ≤ 0.3, all Zr1-xNi2+xGa compounds demonstrated superconducting behavior, but no superconductivity was observed in the Zr1+xNi2-xGa alloys for x > 0.2. The magnetization data revealed that all materials in both Zr1+xNi2-xGa and Zr1-xNi2+xGa series exhibited type-II superconductivity. With increasing doping concentration x, the paramagnetic ordering were enhanced in both systems while the superconducting properties were found to weaken. The observations are discussed considering the structural disorders in the systems.
