Barkhausen
웹2016년 6월 1일 · 1. Introduction. Barkhausen jumps are discontinuous changes in magnetization which occur in a ferromagnetic material subjected to a time-varying magnetic field. These local magnetization changes give rise to an electromagnetic noise-like signal which is termed the Barkhausen noise, after the discoverer, Heinrich Barkhausen, who … 웹巴克豪森效应（英语：Barkhausen effect）指将铁磁材料从退磁状态加磁场磁化到饱和，在中间阶段，铁磁材料是以磁畴突然长大，不可逆和不连续位移过程实现磁化的。磁畴的这种运 …

In electronics, the Barkhausen stability criterion is a mathematical condition to determine when a linear electronic circuit will oscillate. It was put forth in 1921 by German physicist Heinrich Georg Barkhausen (1881–1956). It is widely used in the design of electronic oscillators, and also in the design of general negative feedback circuits such as op amps, to prevent them from oscillating.
