title = "Magnetic domain instability and the equation of state for magnetars: A new mechanism for SGRs",
abstract = "We explore the possibility that soft gamma-ray repeaters (SGRs) and anomalous X-ray pulsars (AXPs) might be the result of a magnetic phase separation in magnetars. Magnetars are thought to be the site for the origin of observed SGRs and AXPs. We study the separation of magnetar-matter into phases of different flux density. We identify the parameter space in matter density and magnetic field strength at which there is an instability for magnetic domain formation. We show that such instabilities are likely to occur in the deep outer crust for the magnetic Baym, Pethick, and Sutherland (BPS) model and in the inner crust and core for magnetars described by the relativistic Hartree theory. We estimate that the energy released by the onset of this instability is consistent with the energy emitted by SGRs.",
