Abstract

Since receiving a short email reporting the superconductor reaching 200 K, we have been working on the reproducing test and the crystal structural determination of the system. We have applied our high-pressure developments for the possible experiments on metallic hydrogen to these experiments. Here we report the progress in last 3+ years including the latest results and our prospective view.
