Abstract
Neutron diffraction experiments have permitted us to locate hydrogen (deuterium) atoms in the compounds Mn23Y6Dx, x = 8.3; 18; 23 whose magnetic behavior is appreciably different from that of the alloy Mn23Y6. No evidence of a Mn-Mn critical distance corresponding to a Pauli-paramagnetic behavior of the hydride (deuteride) has been found.
Résumé
La localisation des atomes d'hydrogène (deutérium) a été déterminée par diffraction neutronique sur les phases de composition Mn23Y 6Dx, x = 8,3; 18; 23, dont le comportement magnétique est sensiblement différent de celui de l'alliage Mn23Y 6. On montre qu'il n'existe pas de distance critique Mn-Mn au-delà de laquelle l'hydrure (deutérure) devient un paramagnétique de Pauli.
