The materials of the Er_<1-x>Dy_xNi system are proposed as new magnetic regenerator materials for use in a 2-stage Gifford-McMahon refrigerator. We produced a series of solid solutions, Er_<1-x>Dy_xNi, by mixing two substances, ErNi and DyNi. These two substances have the same crystal structure and their easy axes of magnetization are perpendicular to each other. The peak in the temperature dependence curve of the magnetic specific heat was observed to broaden, as the concentration, x, of the Dy ions increased above x=0.075. We have demonstrated that mixtures of ErNi and DyNi, which have different easy axes of magnetization, lead to materials with broad peaks in the temperature dependence curve of the magnetic specific heat.
