“…The obtained lattice constants are almost equal between the two alloys and the two magnetic states. In addition, the obtained relaxed value of the AF state in Nd 6 Fe 13 Ga is almost the same as the experimental value (a = 8.069 Å and c = 22.937 Å, 18 the differences are about 0.8%).…”

We studied the stable magnetic structure of ordered Nd 6 Fe 14−x Ga x (x = 0, 1) alloys, which appears in the grain-boundary (GB) phase of Nd-Fe-B permanent magnets, using first-principles techniques. Slight Ga doping (x = 1) was shown to contribute to the stabilization of an anti-ferromagnetic (AF) state, whereas the non-doped case (x = 0) was revealed to favor ferromagnetic state rather than AF state with a slight energy difference.

“…23. The reader should pay attention to the fact that the AlB 2 -type blocks do not have the NdAl 2 stoichiometry as they have the related LnGa 2 (Haszko, 1961), Nd(Al x Ga 2 À x ) (x = 0.2; Martin et al, 1980) and Nd(FeGa) at 773 K (Li et al, 2009). Whilst in LnGa 2 the graphene-like layer is formed by the Ga atoms, in NdAl 11 O 18 , however, such layers are formed by both Al and Nd atoms.…”

# 2015 International Union of Crystallography Neodymium aluminate coatings have been prepared in-situ by the laser zone melting (LZM) method, using a CO 2 SLABtype laser emitting at 10.6 mm. Polycrystalline Al 2 O 3 commercial plates have been used as substrates, and coatings were prepared from the corresponding mixtures of powdered neodymium and aluminium oxides as starting materials. Microstructure, studied by SEM and phase composition, studied by XRD, proved the in-situ formation of a NdAlO 3 / NdAl 11 O 18 eutectic. As a result, a well integrated composite coating was formed. Nanoindentation tests are consistent with excellent integration between coating and substrate. Structural similarities between the eutectic components within the coating, as well as between these and the substrate, are consistent with the crystallographic concepts proposed by Vegas (Ramos-Gallardo & Vegas, 1997), where cation subarrays play an important role governing metal oxide structures. These structure sublattices are suggested as the driving force behind eutectic oxide formation.
