Abstract

Le domaine général de l'invention est celui des circulateurs et isolateurs hyperfréquences comportant trois voies métalliques (11, 12) disposées en Y et un noyau central (14) en ferrite. Au moins la partie centrale du substrat est un hexaferrite de baryum et /ou de strontium dont une partie des ions baryum et/ou une partie des ions strontium a été substituée par des ions lanthane et une partie des ions fer a été substituée par des ions cobalt, la formule chimique générale dudit hexaferrite de baryum-strontium étant BaxSryLazFe12-wCowO19, la somme des indices x, y et z étant égale à 1, l'indice x étant compris entre 0 et 1, l'indice y étant compris entre 0 et 1, l'indice z étant compris entre 0 et 0.5 et l'indice w étant compris entre 0.05 et 0.4.
