Fig. 3: Superconducting behavior of (La,Y)H10 during decompression and comparison with literature.
From: X-ray-diffraction and electrical-transport imaging of superconducting superhydride (La,Y)H10
A Temperature-dependent four-probe DC resistance measurements of (La,Y)H10 collected at multiple pressures during decompression from 153 to 136 GPa, using an excitation current of 0.1 mA. The curves represent the average four-probe resistance, calculated as shown in the inset to eliminate thermoelectric offsets. Distinct drops in resistance indicate superconducting transitions that persist across the entire pressure range. B Critical temperature (Tc) as a function of pressure for LaH10 and (La,Y)H10 hydrides. Open symbols represent Tc values of LaH10 and (La,Y)H10 reported in the literature9,10,11,12,22. Solid symbols indicate Tc values of (La,Y)H10 obtained in this work.
