Effect of heat treatment on residual stresses in ferromagnetic layers

Conclusions

Heating results in a decrease of the residual stresses in electrodeposited ferromagnetic layers. Depending on conditions, the optimum heat-treatment temperature resulting in a minimum residual stress level could be determined. The effect of an increase in the residual stresses after exceeding the optimum temperature can be ascribed only to physicochemical processes taking place during heat treatment since heat treatment in vacuum [3] did not increase these stresses.

The appearance of the magnetomechanical effect in the temperature range where hydrogen is vigorously discharged [5] indicates that the hydrogen content in the electrodeposit plays a foremost rôle in the blocking of the walls.
