Projekt Scale2PM der TU Darmstadt gemeinsam mit Fraunhofer IWKS gestartet

Permanentmagnete auf Basis von Seltenen Erden (SE) erhöhen u.a. die Effizienz von Generatoren in Windkraftanlagen und Motoren in Elektrofahrzeugen signifikant. Sie sind somit für eine erfolgreiche Energiewende unerlässlich. Doch die Versorgung und der Abbau von SE wird von der EU als sehr kritisch eingestuft. An diesem Punkt setzt das aktuell gestartete Projekt Scale2PM der Technischen Universität Darmstadt gemeinsam mit der Fraunhofer-Einrichtung für Wertstoffkreisläufe und Ressourcenstrategie IWKS an: Ziel ist es, ein neuartiges Herstellungsverfahren zu validieren, um Permanentmagnete mit besseren oder gleichwertigen Eigenschaften bei verringertem Ressourceneinsatz zu produzieren.

A new instrument has been installed at beamline ID12 for simultaneous measurements of microscopic and macroscopic magnetic properties. It combines synchrotron-based techniques such as X-ray magnetic circular dichroism and X-ray diffraction with laboratory techniques such as magnetisation, magnetostriction, magnetocalorics and magnetoresistance.

New publication

La-Fe-Si-based alloys represent a promising material class for magnetocaloric cooling at ambient temperatures, but contain highly oxophilic elements and are chemically sensitive, which impairs their continued operation in aqueous heat exchange media.

International research team publishes universal framework in the journal Science

Novel materials are the key for our transition to a more sustainable economy.

Powerful magnets can be used for effective cooling, heat and power generation.

New publication

Bonded permanent magnets are key components in many energy conversion, sensor and actuator devices.

We congratulate our colleague Kilian Schäfer to the Best Poster Award at MSE 2022.

Researchers use multicomponent alloys to make strong and ductile soft magnetic materials. Latest results now published in the journal Nature

Soft magnetic materials (SMMs) applied in electric engines transform energy from sustainable resources into electricity. Conventional SMMs, which are currently used in industry, are prone to damage under severe mechanical loads.

FM members including Prof. Oliver Gutfleisch joined the DPG Meeting of the Condensed Matter Section in Regensburg from 4 to 9 September.

New publication

Both Nd-Fe-B and Nd-Co-B nanocrystalline magnets exhibit coercivity above 1 T.

New publication

Why can a 2nd order magnetocaloric material have “giant” magnetocaloric effect near the condensation point of hydrogen?

Our new 4-year ‘Puma’ project – PUlsed high MAgnetic fields for new functional magnetic materials – is sponsored by BMBF and lead by Dr. Konstantin Skokov.

We congratulate our colleague Dr. Franziska Scheibel.

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 Cox) 78 B 7 (x = 0 – 1) hot-compacted permanent magnets.

Joint publication of several CRC/TRR 270 projects

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.
