Abstract
Various measurements are performed to investigate the spectra of clustered Barkhausen transitions in technical steel. These spectra are formed by the discontinuous jumps of magnetization in the material, when the external magnetic field is changed with relatively high speed. The methods used include power, amplitude and autocorrelation spectra and their magnetization and temperature dependences. A differential correlation is shown to exist between the optically measured grain size and the different spectra, thus confirming the basic principle of a recently proposed electronic differential grain-size analyzer for technical steel.Keywords
