Stress relaxation in the glass bonded ferrites under various cooling conditions was studied. Warp of the glass bonded ferrites was released by holding at a suitable temperature during cooling. The extent of warping as a function of holding temperature gave a V-shape curve whose maximum value was the same as that for warping without anneling. The temperature giving the minimum value was near the T_g of each glass under the condition that holding time was 0.5h. The stress relaxation process and slope of the V-shaped curve were discussed using the thermal expansion curves of the glass and the ferrite and the viscosity curve of the glass. A new method to decide the setting point using the V-shaped curve was also introduced.
