Heinrich Barkhausen: A Short Biography

Heinrich Georg Barkhausen Stamp - RF CafeHeinrich Georg Barkhausen (1881-1956) was a German physicist who made important contributions to the study of electromagnetism and solid-state physics. He is best known for his discovery of the Barkhausen effect and Barkhausen noise, which occur in ferromagnetic materials.

Barkhausen studied physics at the University of Berlin, where he earned his doctorate in 1907. After working as a research assistant for several years, he became a professor at the Technical University of Dresden in 1920.

In 1919, Barkhausen discovered the phenomenon of Barkhausen noise, which is the noise caused by the movement of magnetic domains in a ferromagnetic material. His work on the Barkhausen effect provided important insights into the behavior of ferromagnetic materials and helped to establish the field of solid-state physics.

Barkhausen also made significant contributions to the study of electrical oscillations and electromagnetic waves. He developed a method for measuring the frequency of high-frequency electrical oscillations, known as the Barkhausen-Kurz method, which is still used today.

During World War II, Barkhausen worked on the development of radar technology for the German military. After the war, he was briefly held as a prisoner of war by the Allies before returning to his academic work. Barkhausen received many honors during his career, including the Max Planck Medal and the Hughes Medal.
