Thermal induced structural and magnetic transformations in Fe 73.5-xCex=0,3,5,7Si13.5B9Nb 3Cu1 amorphous alloy

Abstract

Structural and magnetic properties of amorphous and partly crystallized Fe73.5-xCex=0,3,5,7Si13.5B9Nb 3Cu1 alloys, were analysed in the temperature ranging from RT to 800 C with scanning calorimetry and magnetometry. The Fe(Si) and Fe(B) structures were identified and characterised with set of crystallization temperatures and activation energies. Also, Curie temperatures for amorphous and for crystalline structures were determined and analysed as functions of Ce content. © 2013 The Author(s).
