ABSTRACT:
The present invention relates to an apparatus which is designed to employ thermal stimulated processes for analyzing relaxation spectra and resonances in materials. The invention is characterized in that at least two coupled excitation fields are applied to the sample of material analyzed along with a programmed temperature variation, to deconvolute during the thermally stimulated recovery stage the global deformation resulting from the excitation stage. In other words, this invention is designed to obtain one by one the individual and elementary relaxation motions responsible for the global deformation, whether these elementary internal motions have a mechanical, electrical or magnetic origin. Moreover, the relaxation spectra for the motions resulting from the coupling between mechanical, electrical and/or electromagnetical excitations are obtained at the same time and are interrelated.
