Le retournement de l'aimantation dans plusieurs couches minces Gd-Co de composition entre 20 et 46 % Gd, déposées par pulvérisation r.f., a été étudié par effet Kerr polaire à λ = 633 mm, sous des champs jusqu'à ± 10 kOe. Les observations à température ambiante montrent que certaines compositions, qui ne correspondent pas à celle pour laquelle une compensation de l'aimantation est attendue (~ 20/80), présentent une forte coercivité inhabituelle, jusqu'à 6 kOe, et des cycles d'hystérésis très carrés qui indiquent une anisotropie perpendiculaire intrinsèque significative. Le tracé de la coercivité en fonction de la composition met donc en évidence des maxima très marqués qui sont attribués à des transitions de structure du sous-réseau magnéti...
