Impact of grain boundary energy anisotropy on grain growth

S. Kiana Naghibzadeh, Zipeng Xu, David Kinderlehrer, Robert Suter, Kaushik Dayal, and Gregory S. Rohrer

Phys. Rev. Materials 8, 093403 (2024) - Published 19 September, 2024

Recent observations of microstructure evolution during annealing revealed that grain growth not only reduces grain boundary area but also dissipates additional energy through a decrease in average grain boundary energy—a feature that isotropic simulations with uniform energy assumption fail to predict. The authors use a threshold dynamics model incorporating anisotropic grain boundary energies to simulate the observed grain growth of polycrystalline Ni. The model predicts an increase in the relative area of low-energy twin boundaries and a decrease in average boundary energy. This study highlights that realistic simulation of grain growth in polycrystals requires anisotropic grain boundary energy implementation.

Kyle Fruhling, Alenna Streeter, Sougata Mardanya, Xiaoping Wang, Priya Baral, Oksana Zaharko, Igor I. Mazin, Sugata Chowdhury, William D. Ratcliff, and Fazel Tafti

Phys. Rev. Materials 8, 094411 (2024) - Published 24 September, 2024

The topological Hall effect can emerge in a material either statically due to the formation of skyrmions or dynamically due to thermal fluctuations. ErMn6Sn6 undergoes a field-induced ferrimagnetic to antiferromagnetic phase transition. At the boundary of this phase transition there is an intermediate phase which is predicted to provide the right environment for the emergence of a significant dynamic topological Hall effect. Therefore, ErMn6Sn6 provides a testbed to investigate the universality of thermal fluctuations as a mechanism of the topological Hall effect.

Intrinsic origins of broad luminescence in melt-grown ZnGa2O4 single crystals

Ymir K. Frodason, Augustinas Galeckas, Vegard S. Olsen, Philip M. Weiser, Zbigniew Galazka, Chris G. Van de Walle, and Lasse Vines

Phys. Rev. Materials 8, 094604 (2024) - Published 18 September, 2024

The authors present a detailed theoretical study of the optical behavior of native defects in zinc gallium oxide based on configuration coordinate diagrams derived from hybrid functional calculations. The resulting predicted luminescence lines are compared with low-temperature photoluminescence spectra measured on zinc gallium oxide single crystals grown from the melt. Based on this comparison, self-trapped holes, Zn antisites, Zn vacancies, and their complexes with Ga antisites are put forward as potential origins of the observed luminescence.

Magnetic compensation in Mn4xCuxN films on SrTiO3(001) with noncollinear magnetic structures

Aoi Hatate, Tomohiro Yasuda, Kenta Amemiya, and Takashi Suemasu

Phys. Rev. Materials 8, L091403 (2024) - Published 25 September, 2024

Mn4N films are promising materials for ultrafast magnetization control via spin currents. Previous studies have shown that adding magnetic elements such as Ni or Co to these films induces magnetization compensation (MC) at room temperature. The authors now demonstrate that ferrimagnetic Mn4N films can also achieve MC at room temperature with a small addition of Cu, marking the first instance of MC being induced by doping with a non-magnetic element. X-ray magnetic circular dichroism and magnetization measurements further reveal that the magnetic structure of Cu-doped Mn4N films differs from that of their Ni- or Co-doped counterparts.

Phys. Rev. Materials 8, 093802 (2024) - Published 26 September, 2024

Diffraction is the most common method for solving unknown crystal structures, but nanoscale heterogeneity poses substantial challenges. Here we train random forest models to predict the crystal system, space group, and lattice parameters from one or more unknown 2D electron diffraction patterns. We apply this architecture to a 4D-STEM scan of over 100 gold nanoparticles, accurately predicting the crystal structure and lattice constants. Our ML architecture significantly accelerates the analysis of electron diffraction patterns, particularly in the case of unknown crystal structures at speeds amenable to live analysis. This work also releases ~360 million simulated 2D dynamical electron diffraction patterns from 36,000 materials, each with 100 unique crystal orientations and 100 specimen thicknesses.
