Abstract

Investigation of thermal properties giant magneto-resistance constituted with an assembly of alternated Mn/Fe layers according to the Mn thickness using the Photothermal Deflexion Technique. We show in this work that the thermal resistance passes by a maximum value for a Mn critical thickness corresponding to the antiparallel ferromagnetic coupling.
