MAGNETIC PROPERTIES OF INTERMETALLIC COMPOUNDS Dy(Fe-Ga)2.

Magnetic properties were investigated in pulsating and steady magnetic fields (up to 150 and 40 kOe respectively) and NMR spectra were taken on isotope **5**7Fe for compounds with 0 less than equivalent to x less than equivalent to 0. 4 at 4. 2 and 293 K. A sharp increase in the coercive force H//c is discovered in compounds containing Ga atoms, the maximum 10 kOe at 4. 2 K being observed for the alloy with x equals 0. 2. From analysis of the Moessbauer spectra the changed orientation of the easy axis in compounds containing Ga atoms in contrast to DyFe//2 is explained.
