Pressure induced superconductivity in the compound ScZrCo
We report on the synthesis and physical properties of a new compound, ScZrCo, which crystallizes in the Ti _2 Ni structure with the space group of ${\rm{Fd}}\overline{3}{\rm{m}}{\rm{S}}$ without a spatial inversion center. The resistivity at ambient pressure shows a semiconducting-like behavior. Fur...

| description | We report on the synthesis and physical properties of a new compound, ScZrCo, which crystallizes in the Ti _2 Ni structure with the space group of ${\rm{Fd}}\overline{3}{\rm{m}}{\rm{S}}$ without a spatial inversion center. The resistivity at ambient pressure shows a semiconducting-like behavior. Furthermore, specific heat and magnetic susceptibility measurements yield a rather large value of Wilson ratio ≈4.47. Both suggest a ground state with correlation effect. By applying pressure, the up-going behavior of resistivity in the low temperature region is suppressed and superconductivity emerges. Up to 36.1 GPa, a superconducting transition at about 3.6 K with a quite high upper critical field is observed. Our discovery here provides a new platform for investigating the relationship between the correlation effect and superconductivity. |
