Effect of cooling rate in [(Fe0.5Co0.5)0.75B0.2Si0.05]100-xNbx alloy system on magnetic properties

다국어 초록 (Multilingual Abstract)

The effect of cooling rate on the thermal stability and soft magnetic properties of[(Fe0.5Co0.5)0.75B0.2Si0.05]100-xNbx (x = 5, 6, 7, 8 at. %) system was investigated. The alloys were producedinto the form of ribbon and cylindrical rod by melt-spinning and injection casting, respectively. Theirstructure, thermal, mechanical and soft magnetic properties were investigated by x-ray diffraction,differential scanning calorimetry, universal testing machine and vibrating sample magnetometer,respectively. All of the alloys were identified as fully amorphous by X-ray diffraction. It turned out thatthe rod samples had exceptionally high saturation fields reaching 3.0 kOe, which is key properties forsensor application. Also, among these Fe,Co-based samples, the Fe35.25 Co35.25 B18.8 Si4.70 Nb6 ribbonexhibits the highest saturation magnetization with 142.1 emu/g.
