We observed simultaneously Stokes I and Stokes V/I profiles of Fe I (5379.574Å), C I(5380.332Å), Ti II(5381.021Å) and Fe I(5383.369Å) using the ZIMPOL II spectropolarimeter at the IRSOL (Istituto Ricerche Solari Locarno) facility. This set of spectral lines covers not only the mid-photosphere but also the deep photospheric layers, where the temperature sensitive C I line is formed. We analyzed ratios and asymmetries of their Stokes V amplitudes and areas. Further, the spectral profiles were analyzed using the SPINOR inversion code (Frutiger et al. 2000) to constrain the temperature structure of the magnetic elements down to deep photospheric layers. In this way, our understanding of the lowest photospheric layers of solar magnetic elements can be tested.
