Additive manufacturing of multicaloric Ni-Mn-Sn by direct energy deposition using gas-atomized powder

Joint publication of CRC/TRR 270 and partners from Beihang University (China)

We report on microstructure, hard magnetic properties and thermal stability of nanocrystalline (Nd 0.85 Ce 0.15 ) 15 (Fe 1-x Co x ) 78 B 7 (x = 0 – 1) hot-compacted permanent magnets.

Once again this year, 16 outstanding students were able to tackle challenging scientific complexes as part of the 31. Erfinderlabor of the Center for Chemistry (ZFC).

New publication

Formation of twins have been recognized as the bottleneck that limit the high-performance of L10-type Mn-Al permanent magnets.

New publication

Joint publications of projects A05, B01, B04 (first author) and B06

Combined approach of neutron and x-ray diffraction for an analysis of chemical order in Ni(Co)MnTi alloys reveals that no Heusler-typical L2 1 order between Ti and Mn is present, but that the phase transition of Co containing samples can be shifted significantly with proper heat treatment.

This work provides a feasible route to obtain anisotropic RE 2 Fe 14 B magnet without containing critical elements of Nd, Pr, Dy and Tb. Instead, high abundance rare earths are used to substitute those with low abundance.

We welcome Dr. Natalia Shkodich and Dr. cand. Teresa Weßels in the CRC/ TRR 270.

Congratulations to Shabbir Tahir from project B08 (Prof. Gökce, Bergische University Wuppertal) for winning the Best Poster Award at the MMM INTERMAG Joint Conference 2022 for his poster “Synthesis and printing of Fe50Rh50 nanoparticle inks– a laser-based route to generate magnetocaloric structures”

New publication in Applied Physics Letters

An analytical expression for the maximum heat a magnetocaloric material can transfer in one cooling cycle has been derived by investigating the operation of a simplified active magnetic regenerator (AMR).

Virtual event from 08 – 10 November 2021 – registration starts 01 September 2021

New publication in Acta Materialia

Ni-Mn-based metamagnetic shape-memory alloys are highly promising for solid-state caloric cooling applications but commonly exhibit structural and functional fatigue during cyclic operation.

The working group Magnetism of the German Physical Society (DPG) has awarded Benedikt Beckmann the Diploma / Master Prize 2021 at the Autumn Meeting of the Condensed Matter Section.
