We study the radio spectra of two magnetars PSR J1550-5418 and J1622-4950. Weargue that they are good candidates for the pulsars with gigahertz-peakedspectra as their observed flux density decreases at frequencies below 7 GHz. Wesuggest this behavior is due to the influence of pulsars' environments on theradio waves. Both of the magnetars are associated with supernova remnants, thusare surrounded by a hot, ionized gas, which can be responsible for thefree-free absorption of radio-waves. We conclude that the GPS feature of bothmagnetars and typical pulsars are formed by similar processes in thesurrounding media, rather than by different radio-emission mechanisms. Thus,the radio magnetars PSR J1550-5418 and J1622-4950 can be included in the classof the gigahertz-peaked spectra pulsars.

Do radio magnetars J1550-5418 and J1622-4950 have gigahertz-peaked spectra?
