The diagnostic contents of the Stokes I and V profiles of about 50 unblended Fe II lines have been explored and used to set new constraints on the temperature structure of magnetic fluxtubes. The simultaneous use of Fe I and II lines makes it possible to determine the temperature in both the upper and lower fluxtube photosphere. The Fe II lines further make it possible to obtain model-insensitive values of the magnetic filling factors. Empirically determined effective Lande factors of most of the unblended iron lines in the visible part of the solar spectrum are presented and compared with the corresponding LS coupling values.
