Abstract

This thesis describes the effect of heat treatment on the magnetic properties of Co-bsaed Amorphous. A sample was chosen as basic composition with Co$\_$82//Si$\_$2//B$\_$16/ of zero magnetostriction. It was made by single roll method with quartz orifice 0.5[mmø], Ar gas pressure 0.6 [kg/cm$^2$] and roll speed 28 (m/sec) and atmosphere is ,Ar gas. We obtained the sample of width 2.4(mm), thickness 45[$\mu\textrm{m}$]. Made sample annealed for the improvement of magnetic propertics at at annealing temperature 325,350,375 and 400$^{\circ}C$ and annealing time 15, 30, 45, 60 and 120min respectiveily. Amorphous ribbon of co-based showed high permeab- ility ${\mu}$=8000∼14000, and became improvement of magnetic properties according to anneal ins temperature and time. Especially. Amorphous sample at 325$^{\circ}C$ ,45min appearanced high permeability ${\mu}$=13, 589 at frequency f= 100Hz. and loss factor was reduced at low frequency with rising anneal ins ti me and temperature more annealed sample than basic sample.
