Аннотация:The magnetocaloric effect, magnetostriction, and thermal expansion of terbium-dysprosium alloys in the region of magnetic phase transitions is experimentally investigated. On the basis of the results obtained, a magnetic phase diagram of Tb-Dy alloys is plotted, the change in magnetoelastic energy in the phase transition from helicoidal antiferromagnetism to ferromagnetism is calculated, and it is shown that this change is responsible for the large heat of transition and the magnetocaloric effect.
