AimsThe goal of this study is to explore a novel method for the solar photospheric magnetic field diagnostics using StokesVwidths of different magnetosensitive Fe I spectral lines.MethodsWe calculate StokesIandVprofiles of several Fe I lines based on a one-dimensional photospheric model VAL C using the NICOLE radiative transfer code. These profiles are used to produce calibration curves linking the intrinsic magnetic field values with the widths of blue peaks of StokesVprofiles. The obtained calibration curves are then tested using the Stokes profiles calculated for more realistic photospheric models based on magnetohydrodynamic of magneto-convection.ResultsIt is shown that the developed StokesVwidths method can be used with various optical and near-infrared lines. Out of six lines considered in this study, Fe I 6301 line appears to be the most effective: it is sensitive to fields over ∼200 G and does not show any saturation up to ∼2 kG. Other lines considered can also be used for the photospheric field diagnostics with this method, however, only in narrower field value ranges, typically from about 100 G to 700–1000 G.ConclusionsThe developed method can be a useful alternative to the classical magnetic line ratio method, particularly when the choice of lines is limited.
