Magnetic field screening in hydrogen-rich high-temperature superconductors.

ABSTRACT: In the last few years, the superconducting transition temperature, T_c, of hydrogen-rich compounds has increased dramatically, and is now approaching room temperature. However, the pressures at which these materials are stable exceed one million atmospheres and limit the number of available experimental studies. Superconductivity in hydrides has been primarily explored by electrical transport measurements, whereas magnetic properties, one of the most important characteristic of a superconductor, have not been satisfactory defined. Here, we develop SQUID magnetometry under extreme high-pressure conditions and report characteristic superconducting parameters for Im-3m-H₃S and Fm-3m-LaH₁₀-the representative members of two families of high-temperature supercondu
