ABSTRACT The search for high-temperature superconductivity is one of the research frontiers in physics. In the sulfur hydride system, an extremely high Tc (∼200 K) has been recently developed at pressure. However, the Meissner effect measurement above megabar pressures is still a great challenge. Here, we report the superconductivity identification of sulfur hydride at pressure, employing an in situ alternating-current magnetic susceptibility technique. We determine the superconducting phase diagram, finding that superconductivity suddenly appears at 117 GPa and Tc reaches 183 K at 149 GPa before decreasing monotonically with increasing pressure. By means of theoretical calculations, we elucidate the variation of Tc in the low-pressure region in terms of the changing stoichiometry of sulfur hydride and the further decrease in Tc owing to a drop in the electron–phonon interaction parameter λ. This work provides a new insight into clarifying superconducting phenomena and anchoring the superconducting phase diagram in the hydrides.

A kind of resonance frequency detection of piezoelectric micro-cantilever is presented, where there is piezoelectric film deposited. The alternating current is put on the film to make it vibrate, and when resonance frequency happens, the amplitude of piezoelectric micro-cantilever reaches the maximal. A series of experiments have been done by the driving power and detecting power designed by ourselves. The experiments show that resonance frequency can be detected by the amplifier, and the amplitude of the resonance frequency is obviously bigger than the amplitude of the other frequency. The maximal amplitude is about 600nm.
