Microstructure and Soft Magnetic Properties of Fe-Zr-(Pt)-Nb-Cu-B Amorphous Alloys

This paper presents the results of investigations into the microstructure and magnetic properties of Fe₈₆Zr₇Nb₁Cu₁B₅, Fe₈₂Zr₇Nb₂Cu₁B₈ and Fe₈₁Pt₅Zr₇Nb₁Cu₁B₅ alloys. The alloys were investigated in their as-quenched state, in the form of thin ribbons with approximate dimensions as follows: width 3 mm and thickness 20 μm. The investigations were performed utilizing Mössbauer spectrometry and X-ray diffractometry. Also, an evaluation of the low-field magnetic susceptibility and measurements of the magnetization versus temperature and magnetizing field were performed.
