Abstract

We have investigated the evolution of pulsars in the (P,Pdot) diagram. We applied detailed model calculations using ohmic decay of the crustal neutron star magnetic field. We find that, after an initial phase with a small braking index, n, pulsars evolve with enhanced torque decay (n ≫ 3) for about 1 Myr. The long term evolution depends on the impurity parameter of the crystalline lattice in the crust.
