Statistical properties of barkhausen noise in thin Fe films

The statistical properties of Barkhausen noise in an epitaxial Fe film grown on MgO have been characterized with magneto-optical Kerr effect measurements. The data reveal that magnetization reversal takes place via sudden jumps between a discrete number of randomly distributed magnetic configurations. The smallest jumps occur on a scale length of 10 &mgr;m and their amplitude distribution can be fitted with a power law: P(DeltaM) = DeltaM-alpha with alpha = 1.1 and DeltaM spanning over several decades.

Soft X-ray Emission Spectroscopy at ESRF Beamline 26 Based on a Helical Undulator.

A new soft X-ray spectrograph for X-ray emission spectroscopy excited by synchrotron radiation is presented. The apparatus is now installed on beamline 26 at the ESRF in Grenoble. A brief description of the beamline is given and then several components of the spectrograph are covered in more detail. Results of experiments performed both with direct non-monochromated undulator radiation and with monochromated radiation are reported.
