摘要：

A combination of Mg-25 and Al-27 NMR has been shown to be an effective structural probe for the intermetallic phase Mg17Al12, able to detect precipitation of this phase in dilute alloys of aluminium in magnesium during age hardening, with well-resolved signals from the precipitate and the alloy. Knight shift and spin-lattice relaxation measurements for the intermetallic phase are examined for evidence of a quasigap at the Fermi surface, recently proposed as the origin for the stability of this phase.
