Study of Structural, Magnetic, and Mossbauer Properties of Dy2Fe16Ga1−xNbx (0.0 ≤ x ≤ 1.0) Prepared via Arc Melting Process

Intermetallic compounds of Dy2Fe16Ga1−xNbx (x = 0.0 to 1.00) were synthesized by arc melting. Samples investigated for structural, magnetic, and hyperfine properties using X-ray diffraction, vibration sample magnetometer, Mossbauer spectrometer, respectively. The Rietveld analysis room temperature diffraction data shows that all the samples crystallized in Th2Fe17 structure. unit cell volume alloys increased linearly with an increase Nb content. maximum Curie Tc ~523 K x 0.6 is higher than 153 Dy2Fe17. saturation magnetization decreased increasing content from 61.57 emu/g 42.46 1.0. Mössbauer spectra showed a small amount DyFe3 NbFe2 secondary phases at field while isomer shift values observed may have resulted decrease s electron density due expansion. substantial thus prepared intermetallic expected implications magnets used high-temperature applications.
