Ultrafast electrons in magnetic oxides: a new direction for spintronics? - TRR227 paper in Nature Communications

Special metal oxides could one day replace semiconductor materials that are commonly used today in processors. Now, for the first time, an international team of researchers from Martin Luther University Halle-Wittenberg (MLU), the University of Kaiserslautern and the University of Fribourg in Switzerland was able to observe how electronic charge excitation changes electron spin in metal oxides in an ultrafast and inphase manner. The study was published in the journal "Nature Communications".
