Аннотация:The structure, magnetic, magnetothermal, and magnetoelastic properties of Gd5Si Ge In2x(x = 0–0.1) intermetallic compounds have been studied in the region of magnetostructural phase transitions.It is shown that introduction of indium creates the effect of negative pressure, leading to a change in the critical temperature of the magnetic phase transition in the monoclinic phase of the compounds studied and topartial separation of the magnetic and structural phase transitions in them.
