The paper presents the results of contactless SQUID-magnetometric studies of single crystals of the FeTe0.65Se0.35 compound saturated with hydrogen at various temperatures. The experimental technique is described. The results of changes in the magnetic and superconducting characteristics under the influence of sorption of gaseous hydrogen are discussed.
