Abstract: The paper shows the effect of homogenization annealing on the ferromagnet-paramagnet phase transition in the GdNi

$_2$ alloy. In the cast sample, at the Curie point, a temperature hysteresis is observed, which in an external magnetic field of 13.5 T can be at least 3 degrees. The data of scanning electron microscopy of the electropolished samples showed a decrease in the impurity phase of GdNi and practically no temperature hysteresis of the phase transition in the annealed GdNi
