Abstract Scope |
In the field of new nanocrystalline, magnetically soft materials, one of the key roles plays the possibility of obtaining materials with the highest possible saturation magnetization. New materials are prepared using new technique of ultra-rapid annealing. High heating rate of 150-200 K/s. This process allows to obtain high saturation magnetization and low coercion field.
The high induction metallic glass ribbons obtained via melt spinning technique with the chemical formula Fe67Co20B13 were investigated. Thermal stability, crystallization and magnetic properties like complex permeability, magnetic saturation and coercivity were studied. Thermal properties: solidus-liquidus curves, the crystallization temperatures and kinetics of the crystallization process were analysed by applying DSC calorimetry. For the samples in the form of toroidal cores, the B(H) dependence were analysed. The X-ray diffraction was used to analyse the crystalline structure evolution. Complex permeability were measured in the function of frequency range up to 110 MHz. |
