The structure and magnetic properties of magnetically soft cobalt base nanocrystalline powders and nanocomposites with silicon binding

The paper will present influence of high energy mechanical milling process and isothermal annealing of cobalt base metallic glasses on magnetic properties and their structure. Investigation were carried out on Co68Fe4Mo1Si13.5B13.5 itd. metallic glass tapes milled with different times of milling and different condition of annealing. Based on the results of magnetic properties measurements and particles size distribution nanocomposites samples with silicon binding was prepared. Results and discussion of the influence of high energy mechanical milling process and isothermal annealing on particle size and their distribution as well as structure and magnetic properties of investigated samples will be presented.
