Abstract: Properties of the GdFeAl compounds crystallizing in the cubic MgCu2-type structure as well as in hexagonal MgZn2-type structure have been compared. The electrical resistivity, ac susceptibility and magnetization in function of temperature revealed relatively high magnetic ordering temperature, ca. 200 K. The differences in magnetization were observed for samples crystallizing in two different crystallographic structures. The magnetic moments measured at 4.2 K and up to140 kOe are very far from the value of the magnetic moment of a free Gd ion. The magnetic moments of cubic and hexagonal phases are 1.1 μB and 1.7 μB, respectively.
