Abstract :
The effects of annealing temperature on the structure and magnetic behavior of mechanically alloyed Fe86.5Zr7B5Cu1.5 powders are investigated. These powders are used to prepare a thick film by the screen printing technique. The crystallized phase and grain size of all the samples are characterized by X-ray diffraction (XRD). Annealing above 500°C increases the crystallite size of the samples in the bcc phase. Also, annealing higher than 500°C, coercivity of the powder samples increases to show a maximum and drops. For the applied field parallel to the film plane, the magnetization of the thick film rapidly increases in the low field region and almost saturates in a field of 4.5 kOe. The sample with thick film form is found to be more easy saturated than the mechanically alloyed powders.
