  The paper estimates the flux of PeV neutrinos from magnetar polar caps,
assuming that ions/protons are injected, and accelerated in these regions and
interact with the radiative background. The present study takes into account
the effect of the photon splitting mechanisms that should modify the radiative
background, and enhance the neutrino flux at PeV energies, with a view to
explain the PeV neutrino events detected in IceCube. The results indicate that
in near future, a possibility of any significant excess of neutrino events from
a magnetar in Milky Way is extremely low.
