Tailoring magnetocaloric effect in all-d-metal Ni-Co-Mn-Ti Heusler alloys: a combined experimental and theoretical study
2020/10/26
Joint publication in Acta Materialia by a team of our CRC/TRR HoMMage, ERC Cool Innov and Helmholtz-RSF Joint Research Group
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.

Induction of uniaxial anisotropy by controlled phase separation in Y-Co thin films
2020/09/30
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.

Experimental and theoretical investigation of the chemical exfoliation of Cr-based MAX phase particles
2020/09/30
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.
