Application of lead alkali-silicate bonding glass to ferrite heads
- 32 Downloads
The residual stress induced in the bonding glass bonded to a ferrite substrate was measured with a photoelastic method. The permeability and the head output showed a maximum at a specific compressive stress. This behaviour was explained by the change of induced anisotropy caused by the magnetoelastic effect.
