1924E. P. T. Tyndall in Physical Rev. XXIV. 439 Barkhausen effect for silicon steel... Barkhausen and Van der Pol consider the effect as due to the sudden re-orientation of groups or chains of molecular magnets. 1925Chem. Abstr. XIX. 1659 Occurrence of Barkhausen oscillations in triodes. 1936R. S. Glasgow Radio Engin. x. 310 (caption) Circuit for generating Barkhausen oscillations. 1940Chambers's Techn. Dict. 76/2 Barkhausen oscillator, a generator of very high frequency oscillation (above 108 cps.), whose action depends on the transit time of the electrons from cathode to anode of a three-electrode valve. Barkhausen–Kurz oscillations, oscillations of very high frequency generated in a triode valve with a positive grid, the anode potential being approximately the same as the cathode. The oscillations are those of electrons passing to and fro through the grid. 1944W. L. Emery Radio Engin. 284/1 (Index) Barkhausen–Kurz oscillator. 1957Encycl. Brit. XIV. 646/1 Barkhausen Effect. In 1919 H. Barkhausen discovered the effect known by his name, and interpreted it as demonstrating that the magnetization of iron proceeds by steps and not in a continuous manner. |
