Phase transformations in Mo-doped FINEMETs

Structural and magnetic study of Mo-doped FINEMET

“…This behaviour was in agreement with the decrease in the thermal stability with the Nb-Mo exchange already reported in Ref. [3]. The increase in the crystalline fraction, however, did not substantially affect the present crystalline sites, i.e.…”

“…The calculated phases' fractions of the nanocrystalline alloys revealed that increase in Mo content led to larger crystalline fractions, in agreement with the detriment of the thermal stability previously reported [3]. Thus, both mean hyperfine field and B augmented with Mo content.…”

“…The consequences in the phase transformations caused by the substitution were studied in Ref. [3] and the magnetostrictive properties were reported in Ref. [4].…”

Heat Treatment Effect On Magnetic Properties Of Finemet-Type Films

“…Second, the smaller atomic radius of Mo can be responsible for the increase in grain sizes as reported for the ribbon in Ref. [9]. .…”

Finemet Thin Films Substituted by Chromium - CEMS and MOKE Study

“…Finemet alloys of original composition Fe 73.5 Cu 1 Nb 3 Si 13.5 B 9 and similar alloys with modified chemical constitution are usually obtained in a form of amorphous ribbons by rapid quenching of melt and optionally they are subjected to the controlled annealing in order to form nanocrystalline structure. The alloys are well-known for excellent soft magnetic properties resulting in many applications [1][2][3][4]. Employment of the form of thin film gives additional possibilities, for instance Finemet substituted by Cr can be used for fabrication of magnetic thin film inductors in high-frequency applications [5].…”
