Article Synopsis
  • Magnetic materials with noncollinear spin textures are important for spintronics, requiring control over their length and energy scales for practical use.
  • The study compares two chiral helimagnets, CrNbS and CrTaS, revealing that while they have similar magnetic-phase diagrams, their electronic band structures differ significantly.
  • Results indicate that CrTaS has stronger ferromagnetic coupling and spin-orbit coupling, which influences the characteristics of their spin textures.

FeSeS remains one of the most enigmatic systems of Fe-based superconductors. While much is known about the orthorhombic parent compound, FeSe, the tetragonal samples, FeSeS with  > 0.17, remain relatively unexplored.

The mechanism of the enhanced superconductivity in monolayer FeSe/SrTiO has been enthusiastically studied and debated over the past decade. One specific observation has been taken to be of central importance: the replica bands in the photoemission spectrum. Although suggestive of electron-phonon interaction in the material, the essence of these spectroscopic features remains highly controversial.

Topological magnets comprising 2D magnetic layers with Curie temperatures (T ) exceeding room temperature are key for dissipationless quantum transport devices. However, the identification of a material with 2D ferromagnetic planes that exhibits an out-of-plane-magnetization remains a challenge. This study reports a ferromagnetic, topological, nodal-line, and semimetal MnAlGe composed of square-net Mn layers that are separated by nonmagnetic Al-Ge spacers.

Article Synopsis
  • Two-dimensional materials exhibit unique properties that differ significantly from their bulk forms, particularly in superconductivity, which is often enhanced by specific substrates or intercalants.
  • Recent research highlights the critical role of surface states in few-monolayer MgB, contributing significantly to the superconducting gap spectrum, distinct from the conventional bulk-like gaps.
  • The study indicates that accessible surface states can lead to superconductivity at higher temperatures, with observed gap openings reaching around 30 K in just six layers of MgB, emphasizing the importance of free surfaces in atomically thin materials for future superconductivity research.
