“…Figure 1 shows the XRD pattern for as-synthesized Cu 2 FeSnS 4 nanocrystals. Obviously, our XRD pattern did not match those reported in the literature [15][16][17] and the standard JCPDS card database (stannite structure, JCPDS no. 44-1476).…”

“…However, Cu 2 FeSnS 4 usually crystallizes in a stannite structure (space group I-42 m, no. 121), and Cu + , Fe 2+ , and Sn 4+ cations have a fixed position in the stannite unit cell [15]. In the previously reports, quaternary Cu 2 FeSnS 4 magnetic semiconductor with a stannite structure exhibited an antiferromagnetic behavior with a Néel temperature (T N ) of 6∼8 K [15][16][17].…”

Diluted magnetic semiconductor Cu 2 FeSnS 4 nanocrystals with a novel zincblende structure have been successfully synthesized by a hot-injection approach. Cu + , Fe 2+ , and Sn 4+ ions occupy the same position in the zincblende unit cell, and their occupancy possibilities are 1/2, 1/4, and 1/4, respectively. The nanocrystals were characterized by means of X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED), energy-dispersive spectroscopy (EDS), and UV-vis-NIR absorption spectroscopy. The nanocrystals have an average size of 7.5 nm and a band gap of 1.1 eV and show a weak ferromagnetic behavior at low temperature.

“…To complete the discussion, antiskyrmions in films with symmetries resulting in a scalar spiralization do not exist, but can be found in bulk crystals with space groups D 2 d and S 4 . The most promising systems to host antiskyrmions seem to be magnetic Heusler alloys (e.g., Mn 2 RhSn 38 ), chalcopyrites (e.g., CuFeS 2 39 ), stannites (e.g., Cu 2 FeSnSe 4 40 ) or kesterites (e.g., Cu 2 Mn 1− x Co x SnS 4 41 ).…”

Chiral magnets are an emerging class of topological matter harboring localized and topologically protected vortex-like magnetic textures called skyrmions, which are currently under intense scrutiny as an entity for information storage and processing. Here, on the level of micromagnetics we rigorously show that chiral magnets can not only host skyrmions but also antiskyrmions as least energy configurations over all non-trivial homotopy classes. We derive practical criteria for their occurrence and coexistence with skyrmions that can be fulfilled by (110)-oriented interfaces depending on the electronic structure. Relating the electronic structure to an atomistic spin-lattice model by means of density functional calculations and minimizing the energy on a mesoscopic scale by applying spin-relaxation methods, we propose a double layer of Fe grown on a W(110) substrate as a practical example. We conjecture that ultra-thin magnetic films grown on semiconductor or heavy metal substrates with C 2v symmetry are prototype classes of materials hosting magnetic antiskyrmions.

“…These spins can order in-phase (ferromagnetic, FM) or out-of-phase (antiferromagnetic, AFM). Stannite structured CFTS has a Néel temperature as low as 6-8 K;42,43 however, its microscopic magnetic structure is not clear. To check the magnetic ordering and its stability, we calculated three magnetic structures for ke-CFTS and st-CFTS.…”

Kesterite semiconductors, particularly Cu 2 ZnSnS 4 (CZTS), have attracted attention for thin-film solar cells. We investigate the incorporation of Fe into CZTS to form the Cu 2 (Zn,Fe)SnS 4 solid-solution for tuning the lattice spacing and band gap. Firstprinciples calculations confirm a phase transition from kesterite (Zn-rich) to stannite (Fe-rich) at Fe/Zn = 0.4. The exothermic enthalpy of mixing is consistent with the high solubility of Fe in the lattice. There is a linear band-gap bowing for each phase, which results in a blue-shift of photo-absorption for Fe-rich alloys due to the confinement of the conduction states. We propose compositions optimal for Si tandem cells.
