Altermagnetism experimentally demonstrated

Ferromagnetism and antiferromagnetism have long been known to scientists as two classes of magnetic order of materials. Back in 2019, researchers postulated a third class of magnetism, called altermagnetism. This altermagnetism has been the subject of heated debate among experts ever since, with some expressing doubts about its existence. Recently, a team of experimental researchers was able to measure for the first time at DESY (Deutsches Elektronen-Synchrotron) an effect that is considered to be a signature of altermagnetism, thus providing evidence for the existence of this third type of magnetism.

A new 'metal swap' method for creating lateral heterostructures of 2D materials

Heterostructures of two-dimensional materials have unique properties. Among them, lateral heterostructures, which can be used to make electronic devices, are challenging to synthesize. To address this, researchers used a new transmetallation technique to fabricate heterostructures with in-plane heterojunctions using Zn3BHT coordination nanosheet. This simple and powerful method enables the fabrication of ultrathin electronic devices for ultralarge-scale integrated circuits, marking a significant step forward for 2D materials research.

BESSY II: Molecular orbitals determine stability

Carboxylic acid dianions (fumarate, maleate and succinate) play a role in coordination chemistry and to some extent also in the biochemistry of body cells. A team has now analyzed their electronic structures using RIXS in combination with DFT simulations. The results provide information not only on electronic structures but also on the relative stability of these molecules which can influence an industry's choice of carboxylate dianions, optimizing both the stability and geometry of coordination polymers.
