Experiment We detail the synthesis and characterization of lanthanum superhydride samples, including four probe electrical transport measurements that display significant drops in resistivity on cooling up to. Here, we report the pressure and magnetic field dependence of the superconducting order observed in lah 10. we determine that the high symmetry high temperature superconducting fm 3m phase of.
Experiment It was the first metal superhydride to be theoretically predicted, [2][3] synthesized, [4] and experimentally confirmed [5] to superconduct at near room temperatures. We have developed a novel preparation technique that is optimally suited for megabar pressure syntheses of superhydrides using modulated laser heating while maintaining the integrity of sample probe contacts for electrical transport measurements to 200 gpa. Room temperature superconductivity has been one of the most challenging subjects in modern physics. recent experiments reported that lanthanum hydride lah 10±x (x<1) raises a superconducting transition temperature tc up to ∼ 260 (or 215) k at high pressures around 190 (150) gpa. In this study we focus on covalently bonded hydrogen clusters in lah 10, 11 euh 9, 37 and uh 8, 45,46 all shown in fig. 1, in order to explain structural trends.

In this work we explore the high pressure phase stability and superconductivity of lanthanum hydrides l a h 𝑚. Here, we discover significant nuclear quantum effects (nqe) in this polyhydride, and demonstrate that a minor amount of stoichiometric defects will cause quantum proton diffusion in the otherwise. Here, we report a systematic computational investigation of the structural and superconducting properties of rare earth (re) polyhydrides formed under pressure across the whole lanthanide series. In this paper, we present the synthesis of seven lanthanum hydrides, as well as two carbon containing compounds, in the range of 50–176 gpa, all characterized by employing scxrd.
