The newly discovered superconductor $\mathrm{U}{\mathrm{Te}}_{2}$ is a strong contender for topological spin-triplet state wherein multicomponent order parameter arises from two nearly degenerate superconducting states. A key issue whether both of these states intrinsically exist at ambient pressure. Through thermal expansion and calorimetry, we show that conditions exhibits detectable transitions only in some samples, the size jump each transition varies when measurement performed different...
Abstract Transition metal nitrides, particularly those of 5 d metals, are known for their outstanding properties, often relevant industrial applications. Among these elements, tungsten is especially attractive given its low cost. In this high‐pressure investigation the W–N system, two novel ultra‐incompressible nitride superconductors, namely W 2 N 3 and , successfully synthesized at 35 56 GPa, respectively, through a direct reaction between in laser‐heated diamond anvil cells. Their crystal...

Despite intense experimental efforts, the nature of unconventional superconducting order parameter ${\mathrm{UTe}}_{2}$ remains elusive. This puzzle stems from reports either a single or double transition at ambient pressure as well complex pressure-temperature phase diagram. To address this issue, we measured heat capacity and electrical resistivity under compressive uniaxial stress $\ensuremath{\sigma}$ applied along different crystallographic directions. We find that critical temperature...
