Dr. Antonio Abate investigates perovskite semiconductors for low-cost and highly efficient solar cells and heads a large research group at the Helmholtz Centre Berlin. Now he has accepted a W2 professorship in the Department of Chemistry at Bielefeld University.
Dr. Antonio Abate has investigated metal-organic perovskite solar cells at HZB since 2017. In 2018, he received an ERC Starting Grant to develop perovskite layers in which less problematic elements can replace environmentally harmful lead. Antonio is also working with his large international team to increase the long-term stability of perovskite materials. Antonio will offer block seminars for students at Bielefeld University.
Spintronics at BESSY II: Domain walls in magnetic nanowires
Magnetic 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.

Fractons as information storage: Not yet quite tangible, but close
A new quasiparticle with interesting properties has appeared in solid-state physics - but so far only in the theoretical modelling of solids with certain magnetic properties. An international team from HZB and Freie Universität Berlin has now shown that, contrary to expectations, quantum fluctuations do not make the quasiparticle appear more clearly, but rather blur its signature.
