Crystal structure, Chemical Bonding, and Magnetism of α-FeGa: How Local Interactions Shape the Structure and Properties of Intermetallic Compounds.

α-FeGa was synthesized from the elements as a polycrystalline powder. Its crystal structure was redetermined by high-resolution powder X-ray diffraction, which showed a complex monoclinic structure of the FeGe type. The determined lattice parameters ( = 10.

MnGaS and MnAlSe van der Waals Chalcogenides: A Source of Atomically Thin Nanomaterials.

Layered chalcogenides containing 3d transition metals are promising for the development of two-dimensional nanomaterials with interesting magnetic properties. Both mechanical and solution-based exfoliation of atomically thin layers is possible due to the low-energy van der Waals bonds. In this paper, we present the synthesis and crystal structures of the MnGaS and MnAlSe layered chalcogenides.

Bulk ferromagnetism in cleavable van der Waals telluride NbFeTe.

A van der Waals telluride, NbFeTe, has been synthesized using chemical vapor transport reactions. The optimized synthetic conditions yield high-quality single crystals with a novel monoclinic crystal structure. Monoclinic NbFeTe demonstrates a (100) cleavage plane, bulk ferromagnetism below 87 K, and a metallic ground state-the necessary prerequisites for needed spintronics technologies.
