Nanocrystallization of soft magnetic Fe(Co)–Zr–B–Cu alloys

Influence of Melt-Spinning Parameters on the Structure and Soft Magnetic Properties of (Fe0.65Co0.35)88Zr7B4Cu1 Alloy

“…[15] Our results are consistent with the preceding observation as the average size of a-Fe particles is nearly the same/slightly increased for both as-spun and annealed conditions. However, the growth of Fe 2 Zr phase is dependent on solidification time.…”

“…Details of the measurement technique can be found elsewhere. [15] Figure 4(c) shows the histogram for It is interesting to note that clusters of nanocrystallites (whose size in the range of 1 to 3 nm) can be observed along with the amorphous phase in the DF image of as-spun ribbon ( Figure 5(b)), which could not be detected in the BF image as well as in the XRD pattern ( Figure 1). The composition of the amorphous phase obtained from EDAX analysis is Fe: 57.3, Co: 29.3, Zr: 7.4, and Cu: 6.0 at.…”

Microstructure and magnetic properties of nanocrystalline Co-doped Sendust alloys prepared by melt spinning

“…It may be caused by the stronger magnetic exchange interaction between Co-Co and Co-Fe than that of Fe-Fe atoms. The results show good agreement with other nanocrystalline Co-doped magnetic alloy systems [20][21][22].…”

Effect of Co or Mn addition on the soft magnetic properties of amorphous Fe89−xZr11Bx (x=5, 10) alloy ribbons

“…The increase in coercivity is most likely due to the induced anisotropy effect [31]. This is the first time experimental results where such ultralow coercivity values are reported in Fe 89ÀxÀy Zr 11 B x Co y ribbons in as-made condition without any post heat-treatment [9,32] Effect of composition variation on T C has been discussed on the basis of the average molecular field model [33]. However, the treatment was focused mainly on materials with either pure ferromagnetic or pure antiferromagnetic state.…”
