Abstract:

The magnetic properties of Er(1-x)U(x)Ga2 intermetallic system single crystals with the hexagonal AlB2 type structure were studied. ErGa2 compound (x = 0) is a collinear antiferromagnet with {[}0 0 1] as easy axis and its Neel temperature (T(N)) is equal to 7.5 K. UGa2 is a ferromagnet with {[}1 0 0] as easy magnetisation direction, its Curie temperature is equal to 125 K. It is shown that the orientations of the easy axes of uranium and erbium subsystems are constant for the whole region of concentrations, but each subsystem has its own ordering temperature. Hence, the Er(1-x)U(x)Ga2 system has the orthogonal magnetic arrangement of erbium and uranium subsystems. The magnetic behaviour of an erbium subsystem can be analysed in the RKKY model taking into account only the difference of electronic concentrations for the different compositions. The magnetic behaviour of a uranium subsystem does not contradict the results of the RKKY calculations.
