Since its first emergence in 2004, the high‐entropy alloy (HEA) concept has aimed at stabilizing single‐ or dual‐phase multi‐element solid solutions through high mixing entropy.

Nature shows its artful side

Novel Ni-Co-Mn-Ti all-d-metal Heusler alloys are exciting due to large multicaloric effects combined with enhanced mechanical properties. We show that an optimized heat treatment leads to very sharp phase transitions in bulk alloys with large isothermal entropy changes.

New collaboration between TU Darmstadt and Max-Planck-Institut für Eisenforschung (MPIE)

The Technical University of Darmstadt and the Max-Planck-Institut für Eisenforschung (MPIE) started a new Max Planck Research Group headed by Prof. Oliver Gutfleisch, Professor of Functional Materials at the TU Darmstadt and scientific director at the Fraunhofer IWKS Materials Recycling and Resource Strategies.

New publication: In this study, molecular beam epitaxy is utilized to stabilize a nanostructured thin-film magnet consisting of a soft magnetic Y2Co17 exchange coupled to hard magnetic YCo5. While, typically, a phase decomposition can be obtained in rare-earth cobalt systems only by the addition of further elements like Cu, Fe, and Zr and complex heat treatments, here we directly induce phase separation by growth kinetics.

New publication: Two-dimensional carbides/nitrides, typically called MXenes, are an emerging member of the ever-growing family of two-dimensional materials. The prediction of a ferromagnetic groundstate in chromium-containing MXenes has triggered growing interest in their chemical exfoliation from Cr-based MAX phases. However, the exfoliation poses serious difficulties using standard etching agents such as hydrofluoric acid (HF). Here, we investigate the exfoliability of Cr2GaC particles by chemical etching with aqueous HF both experimentally and theoretically.

New publication: Owing to electric-field screening, the modification of magnetic properties in ferromagnetic metals by applying small voltages is restricted to a few atomic layers at the surface of metals.

New publication: Recently 1:12 magnets of Sm-(Fe,V) have shown promising coercivities and the potential to be alternative rare-earth-lean permanent magnets.

New publication: Measurement of the magnetization of SmFe 11 Ti single crystals along the principal crystallographic directions in steady (14 T) and pulsed (43 T) magnetic fields

Online event co-organized and co-sponsored by CRC/TRR 270
