EFFECT OF GLASS REMOVAL ON THE MAGNETIC-BEHAVIOR OF FESIB GLASS-COVERED WIRES

Amorphous magnetic glass-covered wires are of interest for basic resea rch and potential applications. Their specific magnetic behavior origi nates in their very small diameters and in the high internal stresses induced during preparation, Removal of the glass cover leads to signif icant changes in their magnetic properties and behavior, thus improvin g their suitability for sensing applications, A thorough study of the changes produced by the glass removal implies the consideration of the changes produced in the internal stress distribution, We propose a me thod for the calculation of the residual internal stress distribution in wires obtained after the glass removal, based on the results of the magnetic measurements. The residual internal stress distribution allo ws us to explain the magnetic behavior of these wires, We also present the advantages of wires obtained after the glass removal from the pra ctical point of view in comparison with those of conventional amorphou s wires.
