In December 2021 Armanghan Naghipour was appointed State Secretary for Science, Research and Equality in Berlin.
On 18 March, she came to Adlershof to get to know HZB.

On Friday, 18 March 2022, the State Secretary Armaghan Naghipour was in Adlershof and visited the HZB.
Accompanied by Jutta Koch-Unterseher, Head of the Research Department in the Senate, and her colleague Ha Mi Le, the State Secretary got to know HZB and some of the researchers.
We have compiled for you a series of pictures of the visit.
- Spintronics at BESSY II: Domain walls in magnetic nanowiresMagnetic domains walls are known to be a source of electrical resistance due to the difficulty for transport electron spins to follow their magnetic texture. This phenomenon holds potential for utilization in spintronic devices, where the electrical resistance can vary based on the presence or absence of a domain wall. A particularly intriguing class of materials are half metals such as La2/3Sr1/3MnO3 (LSMO) which present full spin polarization, allowing their exploitation in spintronic devices. Still the resistance of a single domain wall in half metals remained unknown. Now a team from Spain, France and Germany has generated a single domain wall on a LSMO nanowire and measured resistance changes 20 times larger than for a normal ferromagnet such as Cobalt.

Ort: Messe München, Halle A3, Stand A3.150/151 - Graphene on titanium carbide triggers a novel phase transitionResearchers have discovered a Lifshitz-transition in TiC, driven by a graphene overlayer, at the photon source BESSY II. Their study sheds light on the exciting potential of 2D materials such as graphene and the effects they can have on neighboring materials through proximity interactions.
