“…1 and 2, primary crystallization starts at the onset point of approximately 500-550°C, which strongly depends on the Ce content. The peaks are well resolved and allow us to calculate crystallization enthalpies and activation energies, along evolutionary procedure [11]. Secondary crystallization starts at about 650°C, and addition of Ce reveals that it is represented by double peaks for Ce 3 and Ce 5 or even by triple peaks for Ce 7 , which suggests complicated structure of the alloy with higher Ce content.…”

“…During the next three runs: when temperature decreases (TM 1down), then increases again (TM 2up) and finally decreases (TM 2down), the M scans run along nearly the same curve, which reveals at least three characteristic regions. The magnetization scans were numerically deconvoluted with evolutionary algorithm [11], by fitting Brillouin functions in these regions. M was measured simultaneously with the corresponding DSC scan, which is shown in the figures with thick-black line.…”

Structural and magnetic properties of amorphous and partly crystallized Fe 73.5-x Ce x=0,3,5,7 Si 13.5 B 9 Nb 3 Cu 1 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.
