Abstract
A SiNx based suspended platform has been developed that allows for the simultaneous measurement of the transport coefficients, namely the resistivity rho, thermopower S, and thermal conductivity kappa. We describe the calorimeter fabrication and the characterization of the set-up required to enable quantitative experiments. The temperature distribution of a typical device is numerically simulated to verify the spatial homogeneity. The method is illustrated for PdxNi1-x and CoxFe1-x ferromagnetic thin films. We employ a novel double bridge technique that allows for an accurate determination of the thermal conductivity.
