We argue that they are good candidates for the pulsars with gigahertz-peaked spectra as their observed flux density decreases at frequencies below 7 GHz. We suggest this behavior is due to the influence of pulsars' environments on the radio waves. Both of the magnetars are associated with supernova remnants, thus are surrounded by a hot, ionized gas, which can be responsible for the free-free absorption of radio-waves. We conclude that the GPS feature of both magnetars and typical pulsars are formed by similar processes","authors_text":"G. Melikidze, J. Kijak, L. Tarczewski, W.
