Triple alloy of gallium, indium, and tin is considered as a prospective material for designing self-healing superconducting micro- and nanoelements. In the present work we carried out studies of (dc) magnetization for the Ga-In-Sn alloy nanostructured due to embedding into a nanoporous silica matrix within the temperature range 1.8-10 K and magnetic fields up to 70 kOe. The alloy composition was close to the eutectic point. Three superconducting transitions were revealed with temperatures 6.24, 5.58 and 3.24 K. Weak superconductivity was observed below 7 K. The transitions were attributed to segregates formed within pores. Magnetic instabilities were found in isotherms of magnetization. Phase diagrams were constructed, and the character of the critical lines was discussed. Keywords: eutectic Ga-In-Sn alloy, nanoconfinement, superconductivity, dc magnetization.
