Barkhausen is also a locality in Detmold, see Detmold-Barkhausen
Heinrich Georg Barkhausen (December 2,1881 – February 20, 1956), born at Bremen was a German physicist.
Born into a patrician family in Bremen, he showed interest in natural sciences from an early age. He studied at the universities of Munich and Berlin before obtaining a doctorate at the University of Göttingen in 1907.
He became Professor for Electrical Engineering at the Technische Hochschule Dresden in 1911 at the age of 29, thus obtaining the world's first chair in this discipline.
He discovered in 1919 an effect named after him, which suggested that ferromagnetic materials contain regions of like-oriented atoms. Induced changes in the magnetic orientation of these domains affect the whole domain and not individual atoms. With suitable equipment, these changes of orientation (jumps) can be heard.
