HZB physicist Jaime Sánchez-Barriga establishes a "Helmholtz-RSF Joint Research Group". Over the next three years he will receive additional funding from the Helmholtz Association and the Russian Science Foundation (RSF) to investigate magnetic quantum materials for future information technologies with partners from the Lomonosov State University in Moscow. In particular, the funding should also enable the exchange and training of young scientists.

Magnetic topological insulators are a unique class of materials which enable spectacular quantum effects, with the most important one being the quantum anomalous Hall (QAH) effect. (Bi,Sb)2Te3 belongs to this material class when its properties are controlled by doping with foreign magnetic elements.

HZB physicist Dr. Jaime Sánchez-Barriga will further develop this material at the synchrotron source BESSY II in collaboration with colleagues from Lomonosov State University, Moscow. The cooperation aims at creating novel ferromagnetic and antiferromagnetic topological materials which could serve as crucial pieces of topological qubits in future information technologies. The resulting QAH material has the potential to function even at room temperature and significantly increase currently available computing speeds by orders of magnitude.

Inauguration of a new beamline

Currently, Sánchez-Barriga and his team have set up a new instrument at BESSY II allowing spin- and angle-resolved photoemission measurements. The inauguration of the new RGBL 2 undulator beamline takes place on 28th of October 2019 followed by a two-day workshop on "Spin-resolved photoemission and electronic structure of quantum and energy materials”. Registrations are possible until October 11th. 

Cooperation with Russian partners has a long tradition at HZB. In 2017, the 15th anniversary of the "Russian German Laboratory" at BESSY II  was celebrated.
