Zusammenfassung:
Recent research on the hydrogen-rich hydrides pushes the superconducting transition temperature (T c) near the limit of room temperature. In the hydrides family, LaH 10 keeps the current record of T c of 250 K. Using a pulsed magnet, we mapped out the phase diagram of LaH 10 under pressure of 140 GPa. The normal state has a linear temperature dependence and high resistance. H c2 has been measured above 60 T. The information on the vortex liquid region, coherence length and density of states are obtained by our measurement, providing valuable information for theoretical and experimental hydride development.
