Abstract: Solar surface magnetism manifests itself in a variety of structures with sizes often comparable or even below our spatial resolution capabilities. Nevertheless, sub-resolution information about the intrinsic atmospheric structure can be obtained via indirect techniques. We use state-of-the-art spectropolarimetric observations in carefully selected photospheric lines which include C I (5380.3 Å) as well as strong lines of Fe I, Ti I covering also the deep layers of the photosphere and obtain ratios of their Stokes V amplitudes. From there we deduce that the temperature within magnetic features is higher at locations of smaller magnetic flux.
