Investigation of the Phase Structure of Tm₂CrFe₁₃Si₃ Compound by Differential Thermal/Thermotravimetric Analyzer

Abstract:

The phase structure and magnetic were investigated by means of x-ray diffraction and differential thermal /thermogravimetric analyzer. The result showed that nitrogenized reaction started at 140oC with little nitrogen diffused into Tm₂CrFe₁₃Si₃ compound. The nitrogen absorption of the Tm₂CrFe₁₃Si₃ compound was most violent at 700oC, and its Curie temperature TC increased obviously. As the temperature increased continually, part of the Tm₂CrFe₁₃Si₃ compound decomposed into TmN compound and α-Fe.
