“…The main disadvantage of these amorphous metal alloys (AMA) was the fact that Curie point exceeds crystallization onset temperature that complicates an effective heat treatment on hysteresis loop shape. In previous our research the amorphous alloys with similar chemical composition Co-(FeMoMn)-(SiB) were investigated and slightly different thermal stability and magnetic properties were revealed [6]. The Curie point of these alloys doesn't exceed crystallization onset temperature, allowing carrying out the optimization annealing.…”

The magnetic properties of the amorphous Co57Fe5Ni10Si11B17 alloy have been studied by a vibrating sample magnetometer. The temperature dependence of saturation magnetization was measured and the Curie point and crystallization onset temperature were determined as 560 K and 760 K respectively. The coercive force was obtained as 200 A/m and saturation magnetization - 65 Am2 /kg. The alloy was produced in the form of a ribbon thickness of 30 µm using the melt spinning method, and its internal amorphous structure was examined by the X-ray diffraction method. The crystallization behavior of the alloy was studied using series of isothermal annealing of the samples of the alloy at temperatures in the range of 723-1023 K for different exposures (up to 240 minutes) and nanocrystalline phases were detected by the X-ray diffraction analysis.
