Thermal resistance investigation of the giant magnetoresistance thin layers by the PTD technique

Abstract

In this paper, we present a thermal properties investigation of giant magnetoresistance 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.
