In this study, we successfully synthesized Mg_xHyTaS₂, in which Mg and H are simultaneously intercalated, by reacting 2H-TaS₂ with MgH₂ as intercalatn under high pressure. Furthermore, by holding this material at a high temperature in nitrogen atmosphere, only hydrogen is removed and MgxTaS2 can be obtained. In our talk, we plan to show detailed explanation of the structure and superconducting properties of these materials.
