L'absence de ferromagnétisme est a priori une condition nécessaire à l'apparition de la supraconductivité conventionnelle [72], hormis pour quelques matériaux [100], et la pression permet ici de contourner ce problème. Toutes les études menées sur YFe 2 H 4.2 et YFe 2 H 5 ont été faites à basse pression d'hydrogène : l'hydrure est synthétisé en enceinte pressurisée, puis étudié sous pression en utilisant un milieu transmetteur différent ,
