dc.description.abstractThe present paper deals with Barkhausen noise emission in Gd. Barkhausen noise emission was investigated in the temperature range mainly below the Gd Curie temperature when the spontaneous magnetization in Gd occurs. Barkhausen noise from the heavy rare-earth Gd is compared with Barkhausen noise emission from the transition metal Co measured at the same magnetizing and other conditions. This study demonstrates that Barkhausen noise emitted from Gd is much weaker than that originating from Co. This is a consequence of different spin exchange interaction among the neighbouring atoms, domain wall thickness as a well as domain wall energies. Moreover, Barkhausen noise is temperature sensitive especially for Gd sample as a result of the altering magneto-crystalline anisotropy.en_US
