Zusammenfassung:Magnetisation and paramagnetic susceptibility measurements are presented for a single crystal of ErZn along the main symmetry directions. Magnetostriction is measured along the 〈100〉 and 〈111〉 directions. From the analysis of the field dependence of the forced magnetostriction at the ordered‐phase the single‐ion and pseudodipolar magnetoelastic interaction parameters associated with the tetragonal distortion are obtained, being respectively M 2γ = 12 K/atom and D 27 ≈ 0.8 K/atom. The transverse magnetostriction along the 〈100〉 direction is analyzed in terms of effective conventional magnetostriction parameters hi. From parastriction experiment values for M 2γ and the quadrupolar effective interaction parameter are deduced, viz. M 2γ = (15 ± 1) K/atom and G1 = (2.5 ± 1) mK/atom. L'aimantation et la susceptibilité paramagnetique ont eté mesurées dans un monocristal de ErZn selon les principales directions de symmetrie. La magnetostriction a eté mesurée selon les directions 〈100〉 et . De l'analyse de la dependence avec le champ magnetique de la magnetostriction forcée – dans le domaine ordoné nous avons obtenu les parametres á un‐ion et pseudodipolaire de l'interaction magnetoelastique, etant respectivement M 2γ = 12 K/atome et D 27 ≈ 0,8 K atome. La magnetostriction transversal selon la direction 〈100〉 est analysée en fonction de paramétres conventionnels effectifs, hi. De la mesure de la parastriction les valeurs de M 2γ et le paramétre l'interaction effectif quadropolaire sont obtenus, M 2γ = (15 ± 1) K/atome et G1 = (2,5 ± 1) mK/atome.
