An internal mechanism for the anti-glitch observed in AXP 1E 2259+586

Abstract
Magnetars are fascinating objects that are thought to be neutron stars powered by their strong internal magnetic fields. Clear evidence of a sudden spin-down was detected in the Anomalous X-ray Pulsar AXP 1E 2259+586, an object cataloged as a magnetar. This event received the name "anti-glitch". In this work we present a simple internal mechanism which could account for the observed sudden spin-down of the star.
