Gutfleisch als Sprecher des FA eröffnete die Sitzung.This recognizes outstanding research at the TU Darmstadt for the substitution of critical raw materials and materials for energy technologies. Within the EU MC-ITN EREAN: European Rare Earth Magnet Recycling Network we reviewed the technologies to recover the REEs from these magnets, including physical processing and separation, direct alloy production, and metallurgical extraction and recovery. 10.1007/s40831-016-0090-4 Welt der Materialien On Saturday, , the FM group participated in the „Welt der Materialien“– Open Day of the Material Science department. Given the current state of technology and projected resource supply, Nd in Nd2Fe14B magnets would experience a significant bottleneck only at a later innovation stage, that is, when magnetic cooling technology would largely dominate the domestic refrigerator and air-conditioning market. Synthesis, morphology, thermal stability and magnetic properties of α'-Fe16N2 nanoparticles obtained by hydrogen reduction of γ-Fe2O3 and subsequent nitrogenation Acta Materialia, 123 pp. His Ph D thesis resulted in various articles which can be downloaded here: Publications Online-Edition of the Thesis Invited talk of Prof. Heiko Wende from the University of Duisburg Essen gave an invited talk entitled: From molecular spin hybrids to magnetocaloric systems: fundamental understanding by element specific investigations, within the Framework of the LOEWE RESPONSE and DFG SPP Ferroic Cooling projects. Wende attracted many people followed by an intense discussion. In this work, the fast, easy and effective reactive crucible melting method was applied to the Ni-Mn-Ga and Fe-Mn-Ga Heusler systems. The pure Mn B sample shows a sharp magnetic transition of 567 K yielding a large magnetic entropy change in a 2 T field change. For this purpose we selected three different Heusler alloys of Nie Mne In with transition temperatures between 200 k and room temperature. Information on common research interests such as in LOEWE Response were exchanged.

Many interested people including younger and older pupils, i.e. We thank Heiko Wende for his excellent talk giving an insight on the topic of spin hybrid systems. Energy dispersive X-ray spectroscopy was used for elemental analysis of phases formed in the crucibles which allowed us to construct parts of the room-temperature phase diagrams of Ni-Mn-Ga and Fe-Mn-Ga systems. It is shown that both the substitution of Co and Fe elements for Mn were found to effectively modify Tc accompanied by a lower magnetization leading to a reduced magnetocaloric effect. The S(T) diagrams of the three materials cover all conceivable shapes and are therefore representative for inverse magnetocaloric Heusler alloys. In the paper we present results from micromagnetic simulations that assess the performance of multi-phase nanostructured permanent magnets, whose cross-section resemble that of a Battenberg cake. Nd-Fe-B permanent magnets have been coated with Dysprosium and annealed at various temperatures to study the impact of the temperature dependent Dy diffusion processes on both the magnetic properties and the microstructure.The workshop provides a platform for scientists and engineers from all over the world working in the field of permanent magnets to get together and discuss their research and ideas on topics including:• High performance magnets• Rare-earth free magnets• Mining, raw materials, recycling• Advanced synthesis• Modelling and characterisation• Coercivity mechanisms• Applications Find additional informations in our IEEE Distinguished Lecture: Ludwig Schultz We thank Prof. Ludwig Schultz from the IFW Dresden/ TU Dresden for his visit and his lecture on the “Interaction of ferromagnetic and superconducting permanent magnets – superconducting levitation” given on the 4th of December 2015. Till end of October 2014 he will stay with us, working on magnetocaloric materials.

Micromagnetic simulations on the grain shape effect in Nd-Fe-B magnets Min Yi, Oliver Gutfleisch, and Bai-Xiang Xu Journal of Applied Physics 120, 033903 (2016); Within the LOEWE RESPONSE project we performed micromagnetic simulations to study the effect of grain shape and defect layer in Nd-Fe-B magnets. By means of magneto-optical Kerr microscopy the phases with stripe domains – an essential feature of an uniaxial magnetic anisotropy – were identified and synthesized by conventional metallurgy. The differences in magnetic properties with substitution are described by calculation of the density of states and interatomic distances. First we comprehensively analyzed the magnetocaloric properties of this model system using calorimetry, magnetometry and direct measurements of the adiabatic temperature change ΔTad and subsequently combined those results into the S(T) diagram. By including a super-hard outer shell we are able to counteract the effects of thermal fluctuations and surface defects, both of which are detrimental to the performance of such permanent magnets. When optimum annealing conditions are applied the improved stability against opposing magnetic fields can be observed in the magnets up to a depth of about 3 mm along the diffusion direction.
