Measurements of the relaxation processes with a high time constant

  • Published:
Acta Physica Academiae Scientiarum Hungaricae

Abstract

A new method is proposed which enables the measurements of the magnetic after-effect in a temperature range where the customary methods are unrealizable owing to the high time constant of relaxation τ > 104 sec. Its usefulness in the study of very slow processes is illustrated by the measurement of extremely low diffusion coefficients of carbon in bcc iron. This method can be used in an analogous way also for measurements of anelastic relaxation.
