On the analysis of the tin-inside-H3S Mössbauer experiment

Abstract

A simple analysis is presented of the particular experiment used to prove the bulk nature of very-high-Tc superconductivity in H3S compound under ultra-high pressure. In the experiment, an internal magnetic field was sensed by the synchrotron Mössbauer spectroscopy in tin placed inside the H2S sample. The experiment showed peculiar anisotropy with respect to the direction of the applied field at first sight. By considering actual experimental geometries and parameters of the experiment, we show that this particular observation is consistent with the expectations for a regular type-II superconductor with Meissner expulsion and pinning.
