Abstract
In this paper, we present a thermal properties investigation of giant magneto- resistance Mn/Fe layers as a function of Mn thickness using the Photothermal Deflexion Technique (PTD). We observe that the thermal resistance reaches its maximum for a Mn critical thickness corresponding to the antiparallel ferromagnetic coupling.
Highlights
Since the 1980’s many researches have been carried out on the magnetic multi-layers containing ferromagnetic and nonmagnetic materials

Summary
Since the 1980’s many researches have been carried out on the magnetic multi-layers containing ferromagnetic and nonmagnetic materials. One of the first manifestations of the new properties of these structures was the observation, in 1986, of an antiferromagnetic coupling between layers of iron in three layers Fe/Cr/Fe epitaxially deposited by molecular jets on AsGa substrate [2]. The thermal properties were determined by the Photo-Thermal Deflection (PTD) technique [8,9,10]
