Abstract Magnetic kagome materials provide a fascinating playground for exploring the interplay of magnetism, correlation and topology. Many magnetic kagome systems have been reported including the binary Fe m X n (X = Sn, Ge; m:n = 3:1, 3:2, 1:1) fa

Abstract Kagome vanadates AV3Sb5 display unusual low-temperature electronic properties including charge density waves (CDW), whose microscopic origin remains unsettled. Recently, CDW order has been discovered in a new material ScV6Sn6, providing an o

Abstract We report a Spectroscopic Imaging Scanning Tunneling Microscopy (SI-STM) study of a DyBa2Cu3O7-δ (DBCO) thin film (T c ~ 79 K) synthesized by the molecular beam epitaxy (MBE). We observed an unusual transfer of spectral weight in the local

Manganese oxide self-organizes on Ir(100) surfaces to form arrays of one-dimensional chains, providing a model system to study emergent magnetic behaviour. Schmitt et al. demonstrate they host chiral magnetism mediated by Dzyaloshinskii–Moriya-enha

The transition from single-layer to bilayer growth of molybdenum disulfide on the Au(111) surface is investigated by in situ low-energy electron and photoemission microscopy. By mapping the film morphology with nanometer resolution, we show that a Mo

Two new pentacyclic triterpene acids, bellericagenin A and bellericagenin B and their glycosides, bellericaside A and bellericaside B were isolated from the stem-bark of Terminalia bellerica and were respectively defined as 2α, 3β, 7α, 23-tetrahyd
