TL;DR: In this article, a lutetium ingot (10 × 5 × 2 mm) reached about 97% by heating at 1600 °C for 8 h with an applied N2 pressure of 0.92 MPa; the initial shape of the bulk metal was maintained in the course of nitridation.

Abstract: Lutetium nitride (LuN), an end member of a new quaternary system Si3N4–SiO2–Lu2O3–LuN, was synthesized by direct nitridation of a lutetium metal. The nitridation extent of the lutetium ingot (10 × 5 × 2 mm) reached about 97% by heating at 1600 °C for 8 h with an applied N2 pressure of 0.92 MPa; the initial shape of the bulk metal was maintained in the course of nitridation. The resulting nitrided lutetium possessed a moderately low oxygen content (∼0.7 wt%), which enables the preparation of uncharacterized high nitrogen-containing phases in the Lu–Si–O–N system.

Electronic structure of rare-earth nitrides using the LSDA + U approach: Importance of allowing 4 f orbitals to break the cubic crystal symmetry
TL;DR: In this paper, the LDA+U method was applied to the rare-earth (RE) nitrides in the rocksalt structure using density functional theory calculations within the local spin density approximation with Hubbard-$U$ corrections.

TL;DR: In this paper, the authors take stock of where progress has occurred within the last decade in both theoretical and experimental fields, and which has led to the point where a proof-of-concept spintronic device based on rare earth mononitrides has already been demonstrated.

TL;DR: In this article, the authors report the electronic structure basis for these observations and discuss the origin of similarities and differences among the lanthanides characterized in that work, along with the features that are well described by a first-principles cluster and surface slab models.

TL;DR: D density functional theory within the framework of generalized gradient approximation has been used to investigate the structural, elastic, mechanical, and phonon properties of lutetium monopnictides in rock-salt crystal structure and it is found that all lutettium monopNictides are anisotropic and show brittle character.

Phase relationships in the system Si3N4-Y2O3-SiO2
TL;DR: In this paper, the role of Y2O3 in the hot-pressing of Si3N4 was discussed in terms of its role in a liquid-phase sintering process which incorporates dissolution and precipitation of Si 3N4 at the solid-liquid interface.
