The Te Mssbauer spectra of FeTe and FeTeSe were measured using synchrotron-radiation-based Mssbauer spectroscopy. The hyper fine field of Te in the antiferromagnetic phase of FeTe was evaluated to be 4(1) T at 20 K, and this hyper fine field is considered to be due to the transferred hyper fine field from Fe magnetic moments. The evaluated hyper fine field was comparatively large, suggesting the strong correlation with the magnetic moment of Fe that forms double stripe type magnetic structure. For the superconductor FeTeSe, no marked change in its Mssbauer parameters was observed below or above the superconducting transition temperature, indicating that the change in the electronic state of Te was small.
