a Calculated thermopower for Py/Cu multilayers in the layer parallel (dashed line) and perpendicular (solid line) directions vs thickness ratio λ=tPy/tCu using Eqs. 1 and 2 and bulk values for transport coefficients. The gray dashed line shows the values for λ= 1; the inset shows a FM/Cu multilayer stack. b Room temperature variation of the electrical resistance and Seebeck coefficient of a Py/Cu NW network in magnetic fields applied in the IP and OOP directions. c MR ratio and MTP as a function of temperature with the field applied in the plane of the NW network films. d Measured Seebeck coefficients at zero applied field SAP (blue full circles) and at saturating magnetic field SP (red open circles), along with the corresponding calculated S (orange triangles) and S (violet triangles) from Eqs. 5 and 6 (see text). The data obtained on a Py NW network (80-nm diameter) are also reported (green squares). The error bars reflect the uncertainty of the electrical and temperature measurements and is set to two times the standard deviation, gathering 95% of the data variation
