The observed long-term spin-down evolution of isolated radio pulsars cannot be explained by the standard magnetic dipole radiation with a constant braking torque. However, how and why torque varies still remains controversial, which is major issue in understanding neutron stars. Many have been significant changes their rates modulated quasi-periodic oscillations. Applying phenomenological model pulsar timing noise we developed recently to precise data stars, here show that evolutions modulations can Hall effects crusts. Therefore crustal fields, rather than cores, dominates long term these young pulsars. Understanding nature not only reveals interior physics but also allows physical modeling thus improves sensitivity gravitational wave detections
