 Annealing at specific temperatures can be used to provide different isothermal relaxations that can be measured by a subsequent heating scan.The sf-TM experiments duplicate experiments that can be performed using differential scanning calorimetry (DSC).A limitation of DSC is that the heat exchange during a process or due to the heat capacity of the material cannot be measured over long times or at slow heating or cooling rates since the finite quantity of heat exchanges will be dispersed over too long a time to be detected.
