  We report the detailed spectral measurements over a wide frequency range of
three pulsars: J1741-3016, J1757-2223 and J1845-0743, using the Giant Metrewave
Radio Telescope, which allowed us to identify them as a new gigahertz-peaked
spectra pulsars. Our results indicate that their spectra show turnovers at
frequencies of 620 MHz, 640 MHz and 650 MHz, respectively. Our analysis proves
that wide-band observations improve the estimation of the spectral nature using
a free-free thermal absorption model and thus allow a more accurate
approximation of the maximum energy in the spectrum. While there is no evidence
as of yet that these objects are associated with a supernova remnant or pulsar
wind nebula, they are good targets for looking for interesting environments in
the future, more sensitive sky surveys.
