摘要：

We compare the magnetic properties of a single crystal of erbium before and after charging with hydrogen to a concentration x equals 0. 035 at. left bracket H right bracket / left bracket Er right bracket . The decrease with x of the Neel temperatures T//N (along the c axis) and T//H (within the basal plane) can be explained by: (i) a change in the electronic structure of the metal, i. e. a decrease of the number of conduction electrons (or of the Fermi level density of states); (ii) a modification of the interaction between itinerant and localized spins. Interesting features are observed for the low temperature transitions towards ferromagnetism. Along the c axis and in zero field there is an increase of the transition temperature T//C with x; for T greater than T//C, the same transition is observed in a finite critical field the value of which is smaller for x does not equal 0 than for x equals 0.
