Recently, in order to find ways to increase the current-carrying capacities of HTSC single crystals of FeTe0.65Se0.35, studies were carried out on the effect of the sorption of gaseous hydrogen on the structure of this type of compounds [8]. Along with structural changes in the crystalline phase, distortions of the crystal lattice of the compound and accumulation of the amorphous state were observed, where the amplitude of the order parameter is locally partially suppressed in the… Expand
