“…Metalloid elements such as Si and B play important role in the formation of the glassy structure and have effect on the glass-forming ability, thermal stability and crystallisation of the metallic glasses. Recent studies also show that minor Cu addition has an effect on the magnetic properties of the Fe-based metallic glasses [7,8]. Co 40.2 Fe 20.1 Ni 6.7 B 22.7 Si 5.3 Nb 5 alloy could be formed as cylindrical rods with diameter of 4.5 mm.…”

The magnetocaloric and magnetoresistance properties of amorphous Co-based (Co 0.402 Fe 0.201 Ni 0.067 B 0.227 Si 0.053 Nb 0.05 ) 100−x Cu x (x = 0, 0.5, 0.75 and 1) ribbons were investigated. Cu additions changed the crystallisation temperature (T x ) and the Curie temperature (T C ). The saturation magnetisation (M s ) and coercivity (H c ) for alloys were in the range of 65.51-38.49 emu/g and 1.99-6.84 A/m, respectively. Under an applied magnetic field change of 2.2 T, the (−ΔS M ) max for (Co 0.402 Fe 0.201 Ni 0.067 B 0.227 Si 0.053 Nb 0.05 ) 100−x Cu x with x = 0, 0.5, 0.75 and 1 are 0.77, 0.71, 0.89 and 0.67 Jkg −1 K −1 , respectively. The values of refrigeration capacity (RC) for the as-spun glassy alloys are comparable with those of previously studied Fe-based metallic glasses such as Fe 80 B 10 Zr 9 Cu 1 , (Fe 0.76 B 0.24 ) 96 Nb 4 and Fe 82 Ni 2 Zr 6 B 10 . In addition, the maximum magnetoresistance (MR) values for (Co 0.402 Fe 0.201 Ni 0.067 B 0.227 Si 0.053 Nb 0.05 ) 100−x Cu x with x = 0, 0.5, 0.75 and 1 are found to be 110, 38, 23 and 1% around the Curie temperatures under an applied magnetic field change of 1 T, respectively. With good RC, negligible hysteresis due to very low coercivity values and large magnetoresistance, these Co-based amorphous alloys can be used as the high temperature magnetic refrigerants and multifunctional applications working in the temperature range of 450-600 K.

“…Fe-based metallic glasses have been frequently examined during the last four decades, even though many scientific works in the recent years have been published, mainly due to their good magnetic properties [1][2][3][4][5][6]. It is known that Fe-based metallic glasses usually exhibit high saturation magnetization, low coercive force and high permeability.…”

“…These results demonstrate that the Fe-based glassy alloys might be seen as potential candidates for many electric and magnetic applications. What is more, some authors try to increase soft magnetic properties of Fe-Nb-B [1], Fe-B-Si-Nb [2], Fe-P-C-B [3], Fe-C-Si-B-P [4] and Fe-Cu-Cr-Mo-C-B-Y [5] alloys by addition of minor alloying elements (e.g. Co, Ni or Cu).…”

“…The results obtained by authors show that the replacement of Nb by Fe and the addition of Co caused that values of the Curie temperature and saturation polarization increase from 346 K to 493 K for Fe 69 Co 8 Nb 7 B 15 Cu 1 alloy and from 1.0 T to 1.4 T for Fe 79 Nb 5 B 15 Cu 1 metallic glass, adequately. Dou et al [2] have revealed that proper substitution of Fe by Cu in Fe 72 − x Cu x B 20 Si 4 Nb 4 (x = 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0) metallic glasses improves the saturation magnetization, coercive force and magnetic permeability.

Thermal and magnetic properties of a recently developed metallic glass of four different compositions [{Co (1Àx) Fe (x) } (0.75) B (0.2) Si (0.05) ] 96 Cr 4 were evaluated, where x = 0, 0.1, 0.2, and 0.3. Coercivity decreased and saturation magnetization increased with the increase in iron content. All alloys showed a high Curie temperature. The trend in thermal stability and magnetic properties was explained by atomic interactions between the constituent elements and s-d hybridization between the ferromagnetic metal and the metalloid atoms.Low hysteresis losses, high saturation magnetization, and low coercivity make Co-Fe based soft magnetic alloys attractive for a number of applications including transformers, motors, sensors, magnetometers, and data recording. [1,2] Magnetic properties of several Co-Fe based nanocrystalline alloys have been investigated for low-loss applications. [3] However, nanocrystalline alloys have grain boundaries, crystalline defects, and different crystal orientations, which limit their use in magnetic applications. In contrast, metallic glasses are free of grain boundaries and have a homogeneous structure, which are potential advantages for developing low-loss soft magnetic materials with controlled properties. High glass transition temperature (T g ) and high Curie point of Co-Fe based metallic glasses are added advantages for high temperature soft magnetic applications. The high Curie point of Co-Fe alloys stems from the strong exchange interaction of magnetic spin between Co and Fe atoms. [4] Therefore, optimum addition of Fe to Cobased metallic glasses may result in enhancement of magnetic properties as well as glass forming ability (GFA).High permeability, [5] excellent mechanical properties, low magnetostriction, and low coercivity are some desirable properties reported for Co-Fe metallic glasses. [6][7][8] The saturation magnetization value for Co-Fe-Ta-B system has been reported to be around 0.5 T with 0.25-0.9 A/m coercivity. Along with good thermal stability, this alloy system exhibits excellent mechanical properties, such as high fracture strength of 5185 MPa. [7,9] Inoue et al. reported the magnetic properties of Co-Fe-Si-B-Nb system with saturation magnetization around 0.60 T and coercivity of 1.55 A/m. [10] Recently, the effect of Cu and Tb (non-magnetic elements) addition on the glass formability and magnetic properties of iron-based metallic glasses has been studied. Addition of Cu and Tb resulted in lowering of glass formability and enhancement of soft magnetic properties. [11,12] However, the change in magnetic properties by systematically changing the iron content in Co-based soft magnetic metallic glasses has not been investigated till date. Furthermore, there are no reports on the magnetization behavior at high temperatures for Co-Fe metallic glasses. Systematic investigation of GFA and magnetic properties for Co-Fe metallic glasses can lead to valuable scientific insight and novel engineering applications.In the present work, the effect of iron content on the gl...
