  We explore the properties of 4110 nuclides from Z = 5 to Z = 82 with the
Sky3D code and the composition of the outer crust in the magnetars under
extreme magnetic fields. The effects of the variation of the nuclear masses due
to the magnetic fields on the outer crust are comprehensively studied. The
neutron-drip transition pressure, the equation of state and neutron fraction in
the outer crust have also been discussed.
